# **Converting Cable Patterns: From Flat to In-the-Round**
## A Complete Guide with Worked Example

### DESCRIPTION
This guide teaches you how to adapt any cable pattern written for straight needles to knitting in the round. Includes general conversion principles and a complete sample pattern (Celtic Cable Cowl) shown both as flat knitting and circular knitting.

---

## MATERIALS

**For Sample Project (Celtic Cable Cowl):**
- **Yarn**: 200m (220 yards) of sport weight yarn
- **Needles**: 3.75mm (US 5) circular needle, 40cm (16") or 60cm (24") length, or size needed to obtain tension
- **Notions**: 
  - Cable needle
  - Stitch marker (for beginning of round)
  - Tapestry needle for weaving in ends

---

## TENSION (GAUGE)

24 stitches and 32 rows = 10cm (4") in stocking stitch on 3.75mm needles

Cable panel (16 stitches) = 6.5cm (2.5") wide

**Always check your tension before beginning.**

---

## FINISHED MEASUREMENTS

Sample Cowl: 48cm (19") circumference × 23cm (9") tall

---

## ABBREVIATIONS

- **k** = knit
- **p** = purl
- **RS** = right side
- **WS** = wrong side
- **st(s)** = stitch(es)
- **rep** = repeat
- **C4F** = Cable 4 Front: slip 2 sts to cable needle and hold in front, k2, k2 from cable needle
- **C4B** = Cable 4 Back: slip 2 sts to cable needle and hold in back, k2, k2 from cable needle
- **BOR** = beginning of round
- **pm** = place marker
- **sm** = slip marker

---

## UNDERSTANDING THE CONVERSION PROCESS

### **Key Principles:**

**1. Right Side vs Wrong Side**
   - **Flat knitting**: You alternate RS rows and WS rows
   - **Circular knitting**: Every round is a RS round
   
**2. Reading Wrong Side Rows**
   - In flat knitting, WS rows are typically purled and read left to right on charts
   - In circular knitting, you eliminate WS rows entirely and work the knit stitches as they appear
   
**3. The Golden Rule**
   - If the stitch appears as a knit on the RS, you knit it every round
   - If the stitch appears as a purl on the RS, you purl it every round
   
**4. Converting WS Rows**
   - Where the flat pattern says "purl" on a WS row, you **knit** that stitch in the round
   - Where the flat pattern says "knit" on a WS row, you **purl** that stitch in the round
   - Cable crosses only happen on RS rows, so they remain unchanged
   
**5. Edge Stitches**
   - Flat patterns often include selvedge/seam stitches
   - Remove these when converting to circular
   - Ensure your stitch count is divisible by the pattern repeat

## SAMPLE PATTERN: CELTIC CABLE

### **Version A: FLAT KNITTING (Original)**

**Cast on:** 34 stitches

**Setup:**
- Edge sts: 1 st each side
- Pattern repeat: 16 sts × 2 = 32 sts
- Total: 34 sts

**Pattern (worked flat):**

**Row 1 (RS):** K1 (edge), *p2, C4B, p4, C4F, p2; rep from * once more, k1 (edge). [34 sts]

**Row 2 (WS):** P1 (edge), *k2, p4, k4, p4, k2; rep from * once more, p1 (edge). [34 sts]

**Row 3 (RS):** K1 (edge), *p2, k4, p4, k4, p2; rep from * once more, k1 (edge). [34 sts]

**Row 4 (WS):** P1 (edge), *k2, p4, k4, p4, k2; rep from * once more, p1 (edge). [34 sts]

**Row 5 (RS):** K1 (edge), *p2, k4, p4, k4, p2; rep from * once more, k1 (edge). [34 sts]

**Row 6 (WS):** P1 (edge), *k2, p4, k4, p4, k2; rep from * once more, p1 (edge). [34 sts]

**Row 7 (RS):** K1 (edge), *p2, k4, p4, k4, p2; rep from * once more, k1 (edge). [34 sts]

**Row 8 (WS):** P1 (edge), *k2, p4, k4, p4, k2; rep from * once more, p1 (edge). [34 sts]

Repeat Rows 1-8 for pattern.

**Stitch Count Verification:**
- Row 1: 1 + (2+4+4+4+2) + (2+4+4+4+2) + 1 = 1 + 16 + 16 + 1 = 34 ✓
- All rows maintain 34 sts ✓

---

### **Version B: IN-THE-ROUND (Converted)**

**Cast on:** 96 stitches

**Setup:**
- No edge stitches needed
- Pattern repeat: 16 sts × 6 = 96 sts
- Join for working in the round, being careful not to twist. Place marker for BOR.

**Pattern (worked in-the-round):**

**Round 1:** *P2, C4B, p4, C4F, p2; rep from * to end. [96 sts]

**Round 2:** *P2, k4, p4, k4, p2; rep from * to end. [96 sts]

**Round 3:** *P2, k4, p4, k4, p2; rep from * to end. [96 sts]

**Round 4:** *P2, k4, p4, k4, p2; rep from * to end. [96 sts]

**Round 5:** *P2, k4, p4, k4, p2; rep from * to end. [96 sts]

**Round 6:** *P2, k4, p4, k4, p2; rep from * to end. [96 sts]

**Round 7:** *P2, k4, p4, k4, p2; rep from * to end. [96 sts]

**Round 8:** *P2, k4, p4, k4, p2; rep from * to end. [96 sts]

Repeat Rounds 1-8 for pattern.

**Stitch Count Verification:**
- Round 1: (2+4+4+4+2) × 6 = 16 × 6 = 96 ✓
- All rounds maintain 96 sts ✓

## PATTERN NOTES

**Notice the Conversion:**

1. **Edge stitches removed**: Flat version has 34 sts (includes 2 edge sts), circular version uses clean multiples of 16

2. **WS rows eliminated**: 
   - Flat Row 2 (WS): P1, *k2, p4, k4, p4, k2*
   - Becomes Round 2: *P2, k4, p4, k4, p2*
   - The knits and purls are SWAPPED because you're viewing from the opposite side

3. **Cable rounds unchanged**:
   - Row 1 (RS) and Round 1 have identical cable instructions
   - Cables always happen on RS

4. **All rounds worked from RS**:
   - You're always looking at the "right side" of the fabric
   - Work stitches as they appear: knit the knits, purl the purls

## COMPLETE COWL INSTRUCTIONS (In-the-Round)

### **COWL BODY**

Using 3.75mm circular needle, cast on 96 sts. Join for working in the round, being careful not to twist stitches. Place marker for beginning of round.

**Ribbed Edge:**
Rounds 1-8: *K2, p2; rep from * to end.

**Cable Pattern:**
Work Rounds 1-8 of Celtic Cable pattern (Version B) a total of 7 times. 
[Pattern section = 56 rounds; piece measures approximately 18cm (7") from cast-on]

**Top Ribbed Edge:**
Rounds 1-8: *K2, p2; rep from * to end.

**Total height: 72 rounds = approximately 23cm (9")**

**Stitch count verification**: Remains 96 sts throughout ✓

### **FINISHING**

Cast off loosely in pattern (k2, p2).

Weave in all ends. Block lightly to open up cable definition.

## CONVERSION CHECKLIST

When converting YOUR cable pattern:

**☐ Step 1:** Identify the stitch repeat (must be a multiple for circular)

**☐ Step 2:** Remove edge/selvedge stitches

**☐ Step 3:** Calculate new cast-on (repeat × number of repeats)

**☐ Step 4:** Keep all RS rows exactly as written

**☐ Step 5:** Convert WS rows:
   - Change "knit" to "purl"
   - Change "purl" to "knit"
   - Work from * to end (not backwards)

**☐ Step 6:** Place marker at beginning of round

**☐ Step 7:** Work pattern, slipping marker each round

**☐ Step 8:** Verify stitch counts remain constant

## TROUBLESHOOTING

**Q: My cable pattern has an odd number of rows. How do I convert it?**
A: Keep the same number of rounds. If the pattern is 10 rows flat, it becomes 10 rounds in-the-round.

**Q: What if my pattern has different cables on different rows?**
A: Cable crosses only appear on RS rows in flat knitting, so they transfer directly to those same round numbers. The even-numbered rounds (former WS rows) will typically be plain rounds with converted knits/purls.

**Q: My stitch count doesn't divide evenly into repeats.**
A: You may need to add balancing stitches. For example, if the repeat is 16 sts but you want 100 sts total, cast on 96 (6 × 16) or 112 (7 × 16) and adjust the circumference accordingly.

**Q: Can I convert any cable pattern?**
A: Most cable patterns convert easily. Patterns with complex shaping or buttonbands may require more adaptation.

## DESIGN VARIATIONS

**Adjust circumference:** Cast on any multiple of 16 sts
- Small (baby hat): 80 sts = 33cm (13")
- Medium (adult cowl): 96 sts = 40cm (16")  
- Large (loose cowl): 112 sts = 47cm (18.5")

**Adjust height:** Simply work more or fewer repeats of the 8-round pattern

**Try different weights:** This pattern works with any yarn weight—just adjust needle size and check tension

---

## SUMMARY

The key to converting cable patterns from flat to circular:
1. **Remove edge stitches**
2. **Keep RS rows the same**
3. **Reverse knits and purls on WS rows** (because you're now viewing from the front)
4. **Work continuously in rounds** instead of back and forth

With these principles, you can convert virtually any cable pattern to in-the-round knitting!
