Why 6?

-- or "Crocheting a hotpad"

It's no accident that the Irish crochet rose started with 6 spokes (and 6 chain loops). Six appears often in circular patterns.

A single crochet spiral hotpad starts with 6 sc sts in the center loop. Then each round after that has an increase 6 sc sts. If you make fewer than 6 increases per round, you'll end up with a cup or bowl shaped object. If you make more than 6 increases, you'll end up with ruffles.

Something similar holds true for double crochet As you recall, a dc st is twice the height of a sc st. To make a circle in dc, you would start with 12 dc sts in the center loop and then increase 12 dc sts per round. For triple crochet, the "magic" number is 18.

In the case of the rose we just completed, we started out with the equivalent of * dc 1, ch 3 * six times. This gave 6 spokes and 6 loops. If we hadn't wanted loops but just a basic pinwheel shape (a circle with spokes), we would have made the equivalent of * dc 1, ch 1* six times – for 12 sts around.

My aunt Ila was my first crochet teacher. And the first thing I ever crocheted was a hotpad. (I didn't start out with long chains of chain sts but rather with something to use in the kitchen.)
Here's the basic pattern:

A Simple Spiral Hotpad
I used Peaches & Creme worsted weight cotton yarn and a size 7 or H (4.50 mm) hook.
The finished hotpad is almost 7" in diameter.

Rnd 1: Ch 2. Sc 6 in 2^nd st from hook. (6 sc)
-- Make a slip knot around the hook. Chain 2. Insert the hook into the second st from the hook (ie, the slip knot) and sc. Make 5 more sc's in the same st (ie, the slip knot).
The out-of-focus photo shows the start of the 4^th sc.

Rnd 2: 2 sc in same st 6x (ie, sc twice in each sc from the previous round). (12 sc)

Rnd 3: * 2 sc in same st, sc 1 * 6x (18 sc)

Note: If you wanted to, you could slip a locking stitch marker into the first st of a rnd to let you know when you're about to start a new rnd.
In the photo, you can see that at the end of rnd 3, there are 18 sts on the outside and that there are 3 rows of sc's.

A lot of patterns for simple spiral hotpads like this have for the next few rounds:
Rnd 4: * 2 sc in same st, sc 2 * 6x (24 sc)
Rnd 5: * 2 sc in same st, sc 3 * 6x (30 sc)
Rnd 6: * 2 sc in same st, sc 4 * 6x (36 sc)

This will produce a hexagon with rounded corners. To get something circular, one needs to vary where one places the increases. Here's a way to do that:

Rnd 4: * sc 2, 2 sc in same st * 6x (24 sc)
Rnd 5: * 2 sc in same st, sc 3 * 6x (30 sc)
Rnd 6: * sc 2, 2 sc in same st, sc 2 * 6x (36 sc)
Rnd 7: * sc 4, 2 sc in same st, sc 1 * 6x (42 sc)
Rnd 8: * sc 6, 2 sc in same st * 6x (48 sc)
Rnd 9: * 2 sc in same st, sc 7 * 6x (54 sc)
Rnd 10: * sc 2, 2 sc in same st, sc 6 * 6x (60 sc)
Rnd 11: * sc 4, 2 sc in same st, sc 5 * 6x (66 sc)
Rnd 12: * sc 6, 2 sc in same st, sc 4 * 6x (72 sc)
Rnd 13: * sc 8, 2 sc in same st, sc 3 * 6x (78 sc)
Make loop: Ch 10 (or more), attach to top of last sc as you would a picot.
Rnd 14: * sc 10, 2 sc in same st, sc 2 * 6x (84 sc), ending with a slip st into the base of the picot-like loop.

For added sturdiness, you can slip stitch along the chain sts. Fasten off.

A final word:
As you work around, you'll find that just before it's time to make an increase, the sts are slanted to the right. After the increase, the sts are slanted to the left.

The way I learned to make hotpads was not to follow a pattern -- but to make an increase when the sts start pulling to the right. (This did work out to about 6 increases per round). Also, if there was a choice about where to place the increase, place it in the middle of a flat edge.
