What a gorgeous block. Thanks for the tute. This is something I want to do at some point in the future.
For those who want to make bias for a project like this and don't have the bias tape maker, you can mark the width you want the bias strips on your ironing board, then insert a straight pin into and out of one side, the into and out of the other side and fold your bias strip into thirds and slip it under the pin. Then as you pull the strip out from under the pin you can iron it and will have bias strips just like you would if you used a bias tape maker - and lots cheaper.
