The Pattern Itself
1. Cast On & Waist Band
- Measure your cat’s waist just behind the front legs.
- With Color A, Ch a multiple of 3 sts to match the measurement (sample: 81 ch for 31cm).
- Check actual length by holding foundation chain to your cat’s waist.
Row 1:
- Ch 2 more for turning.
- Skip 2 ch from hook, in next st: (dc, ch 1, dc) all in same st, skip 2 ch, rep (dc, ch 1, dc) every third ch to end.
- In last ch, dc once.
- Ch 1, turn. Fasten off Color A.
If you’re new to patterns: Start with a chain to match your cat’s size. Work a V-stitch (dc, ch 1, dc) every third stitch across.
2. Tulip Row (Petals)
- Attach Color B in any ch-1 sp (between 2 dc of a V-st).
- Ch 3 (counts as dc), 3 dc in same sp (4 dc total in sp).
- Remove hook, insert into top of beg ch-3, pull through loop to close “tulip.”
- Ch 2, skip to next ch-1 sp, work 4 dc, close tulip, ch 2, rep to end.
- Fasten off Color B.
This row creates raised “flowers” for the vest. Each tulip is 4 dc closed together in one space, then chained to the next.
3. Single Crochet Stabilizer Row
- Attach Color A at start of row one.
- Ch 3, sc in each dc of previous row across.
- At end, dc in beg ch-3 of row below.
- Ch 3, turn.
Here you’re making a solid support row to help the vest keep its shape.
4. Herringbone Section
Rows 4–5 (using Color A):
- Ch 3, turn.
- In each st across, work HBdc (herringbone double crochet). Repeat for two rows.
These rows provide flexible structure and texture. Use the special HBdc technique for extra firmness.
5. Body Shape Increases
Row 6:
- Ch 3, turn.
- (2 dc in next st, skip 1 st) across, ending with 1 dc in last st.
Row 7:
- Ch 1, turn. Sc in each st across.
You’ve made the vest a little wider at the top for comfort, and stabilized with single crochets.
6. Chest/Neck Shaping
- On Row 8: Use stitch markers to leave 16 sts free at each side (center ⅓ of vest for chest piece).
- Join Color A at right marker.
- Ch 4, skip 1 st, dc, ch 1, dc in same st, rep to left marker.
- Ch 1, turn.
Row 9:
- Sc across to end (at left marker).
The chest section ties the vest together at front, with open V-sts as before, sc row for stability.
7. Continue for Chest Section
- Repeat Rows 8 and 9 (“tulip stitch row” and “sc row”) until you have a total of 8 chest rows (approx. Row 15).
You’ll have a slightly narrower band for the neck that will button around your cat’s front.
8. Neck Band/Buttonhole Closure
- Measure your cat’s neck
- Ch a multiple of 3 st to equal neck circumference (sample: 21cm).
- Ch about 10 extra for overlap.
- Join foundation chain to left side of vest (RS facing) with a sl st, then sl st back across vest edge to secure.
This makes a loop that will wrap with buttonholes to fasten securely but comfortably at your cat’s neck.
9. Replicate First Row Pattern At Neck
- With Color A (or Color B for contrast), work (dc, ch 1, dc) in third ch from the hook, skip 2, rep across new neck band.
- Turn and repeat tulip flower row as before (see Step 2).
- Fasten off.
10. Buttonhole Band
- At one edge of the neck band, sc, ch 3, sc for buttonholes, with 2–3 evenly spaced along the side.
- Sc evenly around outer edge, ch 6 at side edge to create leash attachment base, continue sc around vest.
You can adjust the buttonhole placement for the best fit on your cat.
11. D-Ring Harness Attachment
- Secure D-ring with yarn at center back of vest.
- Sc around D-ring for several stitches (approx. 8 sc).
- Leave long yarn tail, sew D-ring base securely to vest center back.
12. Leash
- With Color C (or A/B), ch to 120cm (for leash length).
- Sc in each ch across for a sturdy, flat cord.
- At one end, join to D-ring with sl st, weave in ends securely.
- Optionally, make a second leash with a decorative contrast color using the same process.
Assembly & Finishing
- Sew on buttons for closure.
- Weave in all loose yarn ends.
- Try the vest on your cat to check fit and comfort.
- Block flat if desired for best appearance.
Once buttons and D-ring are attached, your vest is complete and ready for outdoor or indoor use with quick leash removal!
Pattern At-a-Glance & Tips
- How to start: Measure your cat, and begin with a chain matching the chest/waist measured.
- Stitches used: ch, sl st, sc, dc, HBdc, (dc, ch 1, dc) V-stitch, tulip (4 dc joined), buttonhole (sc, ch 3, sc).
- Pattern correction: If neck/circumference doesn't fit, simply increase or decrease the starting chain.
- Tips: Test fit often. Use tight stitches for security. Don't skip the single crochet rows—they stabilize the vest.
