Tumbling blocks question
I am thinking of purchasing the book byABC tumbling blocks by Marci Baker. My question is do I need the clear triangle ruler that she sells? Or does a regular ruler work also? I imagine it is a little harder do use though. I was going to place the order but it is more expensive than I thought it was. Don't know if I want to spend all that money on a ruler. I would probably use it again though, just wondering. Beth
