I use squares and havn't seemed to notice too much bulk. I also ran across something called quilt patties. I got them half price at a quilt show, but I would gladly have paid full price for them! If I were on a bujet like I am trying to be I would try to make plastic templetes out of butter bowl lids, The plastic made a huge diffrence for me!
I have hundreds of paper templets ran off in a couple diffrent sizes. If anyone wants them for the shipping I will gladlt forward them to you. It will save on ink and paper for you. I just hate to waste paper,
