While there are a couple of tutorials online, none of them address how to increase at the proper rate to get a circular shape. We thought we'd cover that here in addition to showing you the technique for working in the round. If you've never done broomstick lace before, we recommend reading over our Basic Broomstick Lace tutorial before you get started with broomstick lace in the round.
Size H-J crochet hook
Two 20-25mm knitting needles
Worsted weight yarn
1. Starting with a chain of 18, cast on the first row as shown in Steps 1-6 of Casting on the First Row on our Basic Broomstick Lace Tutorial.
2. Insert hook under the first 3 loops on the knitting needle.
3. Yarn over and pull a loop through all 3 loops. Chain 1 and work 6 single crochets the top of the group of loops.
4. Crochet off the rest of the row in the same way, removing 3 loops from the knitting needle and working 6 single crochets in the top of each group of 3 loops, until all the loops are off the knitting needle. Join with a slip stitch in the first single crochet to complete the round. You now have twice as many stitches as you did when you started, and you'll notice how the row naturally curls into a circular shape.
5. For the next row, cast half of the stitches onto the knitting needle.
6. Take a second knitting needle of the same size, point it in the opposite direction as the first, and begin casting on the remaining stitches.
7. Cast off the stitches from the second knitting needle first in the following pattern: Remove 6 loops from the needle, work 6 single crochets in the top of that group of loops, remove 3 loops from the needle, work 6 single crochets in the top of that group, remove 3 loops again, work 6 single crochets in the top of that group. Repeat the entire sequence until all the loops are removed from the second knitting needle.
8. Repeat the same sequence described in step 7 to remove all the loops from the first knitting needle. Again, join with a slip stitch to complete the round.
9. Each subsequent round is worked in the same way as in steps 5-8, but the pattern for crocheting off loops changes slightly with each round to maintain a flat circle. The patterns are as follows:
Rnd 1: 3 loops with 6 sc throughout the round
Rnd 2: 6 loops with 6 sc, (3 loops with 6 sc) twice - repeat entire sequence throughout round
Rnd 3: (6 loops with 6 sc) twice, (3 loops with 6 sc) twice - repeat
Rnd 4: (6 loops with 6 sc) 3 times, (3 loops with 6 sc) twice - repeat
Rnd 5: (6 loops with 6 sc) 4 times, (3 loops with 6 sc) twice - repeat
Rnd 6: (6 loops with 6 sc) 5 times, (3 loops with 6 sc) twice - repeat.
And so on...
10. Once your circle is as large as you'd like it to be, you'll want to do something about that gaping hole in the center of it. Thread the tail from the beginning chain through a tapestry needle and insert it in the last chain of the beginning chain.
11. Weave the needle in and out of all the chain stitches in the beginning chain.
12. Remove the needle and pull the tail tight to close the hole. Knot it and weave in the end.
