These half hexagons have sharp corners and are fiddly to do. To give myself a break with hand sewing, I started crocheting a doily.
This Wheat & Grape Doily has 30 rounds and I am on round 15 at the moment. I picked up a second hand book called Heirloom Doilies - A Collection of Favorite Crochet Patterns by House of White Birches and the doily pattern is on page 125.
You can also find this pattern free on-line when you join the Celt's Vintage Crochet and here is their web address http://groups.yahoo.com/group/celtsvintagecrochet/.
