I have a template for that pattern. I found it somewhere online. I have fooled with it some and have made 2 blocks that don't lay flat. I am still messing with it. Someone posted a picture of hers on here 2 or three years ago. I think Jinny Beyer has it in one of her books, but she calls it something else. I found it a couple of years ago, It might have been her Christmas book. I got it from the library. Like I said I am having trouble getting them together right. I have a stack of 40 purple FQ that were given to me that I want to use to make this. I want to get the book to try and look at the instructions.
