I don't have the computer program. I'm using the book only, as well as what folks post here, and a site that has some instructions for each block. The site is sometimes helpful, but other times seems more confusing to me. It is 'doable' without the software but maybe it's not as easy or precise. ?? I photocopy some of the blocks onto paper piecing paper then paper piece it, I photocopy some of the blocks onto regular printer paper and learned to English paper piece, and I trace then applique some of the blocks. I didn't want to have any software issues so stuck with using the book only. Anyone else using the book only that could also comment?
