Skill Level

Beginner to Easy Intermediate

You should know how to:

• Chain (ch)
• Single crochet (sc)
• Slip stitch (sl st)
• Work in the back loop only (BLO)
• (Optional) Seam with whip stitch or slip stitch

Finished Size and Sizing Tips

These arm warmers are made of two ribbed tubes with optional shaping for the wrist and forearm.

How to Choose Your Size

Measure:

1. Wrist circumference
2. Forearm circumference around the widest part you want covered
3. Length from wrist to where you want the sleeve to end

Because ribbing stretches, aim for negative ease:

• Make circumference 1 to 2 in (2.5 to 5 cm) smaller than your actual measurement for a snug fit.

Suggested Sizes (Finished Circumference)

• Small: 6.5 in (16.5 cm) wrist, 8 in (20 cm) forearm
• Medium: 7.5 in (19 cm) wrist, 9 in (23 cm) forearm
• Large: 8.5 in (21.5 cm) wrist, 10 in (25.5 cm) forearm

Length Options

• Short: 8 in (20 cm)
• Classic: 10 in (25 cm)
• Long: 12 in (30.5 cm)

What You’ll Need

Yarn

• Worsted weight (Category 4) acrylic or wool blend for comfortable stretch
• Amount:
  • Short pair: 110 to 140 g (about 180 to 230 m)
  • Classic pair: 140 to 180 g (about 230 to 300 m)
  • Long pair: 180 to 220 g (about 300 to 370 m)

If you are using a lighter yarn, you will need more yardage and possibly more ribs.

Hook

• 5.0 mm (H/8) hook for a medium fabric
• Optional: 4.5 mm if you crochet loosely and want tighter ribbing

Notions

• Stitch markers (2)
• Yarn needle
• Scissors
• Measuring tape

Abbreviations

• ch = chain
• sc = single crochet
• sl st = slip stitch
• BLO = back loop only
• rep = repeat
• st(s) = stitch(es)

Gauge (Helpful, Not Stressful)

Knit-look ribbing varies by tension. Instead of a strict gauge, use this quick check:

Make a swatch:

• Ch 11
• Row 1: sc in 2nd ch from hook and across (10 sc)
• Row 2+: ch 1, turn, sc BLO across (10 sc) for 10 rows

Target: ribbing should stretch nicely and rebound.
Also, measure the width of one rib. This helps estimate how many ribs you need around your arm.

Time Planning at a Glance

These times assume worsted yarn and a 5.0 mm hook, beginner pace.

• Swatch and measuring: 10 to 15 min
• Wrist cuff ribbing (per warmer): 25 to 35 min
• Body to forearm length (per warmer): 45 to 70 min
• Seaming (per warmer): 15 to 20 min
• Finishing touches (pair): 10 to 15 min

Total time for a pair: about 2.5 to 4.5 hours, depending on length and speed.

Pattern Overview

You will:

1. Crochet a ribbed rectangle (this becomes the tube)
2. Seam it into a cylinder
3. Add an optional thumb opening or shaping
4. Finish edges neatly

This creates that “knitted sleeve” look using crochet.

Step-by-Step Instructions

Step 1: “Neckline” Step (Wrist Opening and Cuff)

A lot of tutorials call the opening edge the “neckline” by habit. Here, it means the wrist opening, which is the fitted cuff.

Size Setup

Choose your cuff height (how tall you want the ribbing from wrist up):

• Standard cuff height: 2.5 in (6.5 cm)
• Tall cuff height: 3.5 in (9 cm)

Foundation chain for cuff height

• For 2.5 in cuff: ch 11 (gives 10 sc rows tall)
• For 3.5 in cuff: ch 15 (gives 14 sc rows tall)

You can adjust: more chains = taller cuff.

Cuff Ribbing (Per Arm Warmer)

Estimated time: 25 to 35 minutes

1. Ch 11 (or 15 for tall cuff).
2. Row 1: sc in 2nd ch from hook and sc across.
3. Ch 1, turn.
4. Row 2: sc BLO across.
5. Ch 1, turn.
6. Rep Row 2 until the ribbed strip wraps around your wrist with negative ease.

How many rows?
Use measurement, not a fixed number:

• Wrap the strip around your wrist. It should meet with a gentle stretch.
• If it is loose, add 2 to 4 more rows and test again.

Join a cuff

• Bring short ends together.
• Sl st through both layers across to form a ring, or whip stitch with needle.

Tip: If you seam with slip stitches, the seam looks tidy and slightly stretchy.

Step 2: Body (Sleeve Length to Forearm)

Now you build the main sleeve length by continuing ribbing, and you can slightly widen it so it sits comfortably on the forearm.

You can do this in two beginner-friendly ways:

• Option A: Continue the same ribbing width, stretch does the work
• Option B: Add a few increased ribs gradually for a gentle flare

I recommend Option B for a sleek fit.

Option A: Straight Tube Body

Estimated time: 45 to 60 minutes (per warmer)

1. Continue working ribbing rows just like before:
   • Ch 1, turn
   • sc BLO across
2. After each row, keep the ribbing attached by seaming later, or keep it a flat pane,l then seam at the end.

Stop whethe n length matches your plan:

• Short: 8 in total
• Classic: 10 in total
• Long: 12 in total

This is the simplest and most beginner-friendly.

Option B: Gentle Flare for Forearm (Recommended)

Estimated time: 55 to 70 minutes (per warmer)

You will add a little width by increasing the ribbing height above the cuff, so the sleeve fits the forearm with less squeeze.

Method: Add extra chains at the start of a row

1. After finishing the cuff ring, continue crocheting flat in rows as before.
2. When you want to widen, do this:
   • At the start of a new row, ch 2 extra (in addition to turning chain)
   • Work sc in 2nd ch from hook and onward, then sc BLO across the row
3. This adds 1 to 2 stitches in height. It makes the tube slightly wider once seamed.

When to add widening

• Add widening once about 1.5 to 2 in above the wrist cuff.
• Add widening 1 or 2 times total.

Sizing guide

• Small: widen one time only
• Medium: widen one time, optional second if needed
• Large: widen twice spaced out

Fit check
As you go, wrap the panel around your forearm area. It should be comfortable and lightly snug.

Step 3: Optional Thumb Opening (If You Want a True Arm Warmer)

If you only want “sleeves,” you can skip this. However, a thumb opening makes them practical and prevents slipping.

Estimated time: 10 to 15 minutes (per warmer)

Placement

• Typically, thumb opening starts about 1.5 to 2.5 in (4 to 6.5 cm) above the wrist edge.

Simple thumb gap method

1. Crochet until you reach the point where the seam would sit.
2. When seaming, leave a gap:
   • Seam from wrist edge upward for about 1.5 to 2 in
   • Skip 1.25 to 1.75 in for the thumb space
   • Continue sewing the rest

Sizing for thumb gap

• Small: 1.25 in gap
• Medium: 1.5 in gap
• Large: 1.75 to 2 in gap

Tip: Place the gap slightly toward the palm side for comfort.

Step 4: Seaming the Sleeve

Estimated time: 15 to 20 minutes (per warmer)

1. Lay the piece flat with rthe ight side facing the way you like.
2. Fold lengthwise so the long sides meet.
3. Seam using one method:
   • Slip stitch seam: insert hook through both layers, sl st along
   • Whip stitch seam: with needle, stitch through edge loops

If you add a thumb opening

• Seam up to the opening
• Skip the opening space
• Seam above it to the top

Try-on check
Turn right-side out, put it on, and check:

• Wrist snugness
• Thumb comfort
• Forearm fit

If it is too tight, consider re-seaming with a looser seam or adding a flare.

Making Time Added to Each Section

• Cuff ribbing: 25 to 35 min
• Body ribbing: 45 to 70 min
• Thumb opening setup: 10 to 15 min
• Seam and finishing: 15 to 20 min

Basic Tips for a Polished “Knitted” Look

• Use BLO single crochet consistently. If you accidentally crochet through both loops, the ribbing look breaks.
• Keep edges straight. Always change 1 and turn the same way.
• Count rows occasionally. This helps both warmers match.
• Choose yarn with bounce. Acrylic blends and wool blends show ribbing beautifully.

Common Mistakes and How to Fix Them

1. Twisted cuff join
   • Cause: joining before checking alignment
   • Fix: lay flat, align ribbing, then seam
2. Wrist too loose
   • Cause: not enough negative ease
   • Fix: remove seam, add 4 to 8 more rows, then re-seam
3. Forearm too tight
   • Cause: same circumference all the way up
   • Fix: add 1 to 2 widening steps or crochet a slightly taller rib section after the cuff
4. Ribbing looks uneven
   • Cause: switching loops or inconsistent tension
   • Fix: slow down, always insert the hook into the back loop only, and keep the stitch height consistent
5. Two warmers do not match
   • Cause: measuring only by eye
   • Fix: write row counts for cuff and body, then repeat for the second

Variations to Personalize

1. Extra Long “Ballet Sleeve”
   • Add length to 12 to 14 in
   • Keep a gradual flare, so it hugs the arm elegantly
2. Lace Accent Edge
   • Add a final round of:
     • sc aroundthe  edge, then
     • (ch 3, sl st) Repeated for a tiny picot look
3. Button Tab Detail
   • Stitch a small 1 in tab and sew on 1 to 2 buttons
   • This adds a boutique feel and looks great for gift-making
4. Textured Upgrade
   • Alternate 4 rows BLO sc with 1 row of slip stitch BLO to deepen the “knit” effect
   • Keep the tension looser for slip stitches so it does not tighten too much
5. Color Options
   • Solid neutrals look expensive and modern
   • Two-tone cuffs create a stylish contrast
   • Self-striping yarn makes it playful without extra work

Finishing Tips (Make It Look Premium)

• Weave ends along the ribs, not across them. This hides the tail.
• Steam block lightly if the yarn allows. Do not flatten the ribbing.
• Match seam placement on both warmers so they look like a set.
• Add a soft label if gifting. It instantly upgrades the presentation.

Tutor Suggestions for (Crochet Sleeves Knitted)

• First, crochet a mini practice cuff with ch 11 and 15 rows. Then stretch it and see how it behaves.
• Next, focus on turning consistency. Turn the same direction every row.
• Also, mark the thumb placement with a stitch marker before seaming. This prevents awkward positioning later.
• Finally, keep notes:
  • cuff rows
  • body rows
  • widening points
  • thumb gap size
    So your second warmer matches perfectly.

Quick Sizing Recipe (Cheat Sheet)

1. Make the cuff strip until it fits the wrist with a slight stretch.
2. For forearm comfort, add 1 or 2 widening steps.
3. Crochet until the desired length, then seam.
4. Leave thumb gap if desired.
