It's addictive. If you like minature log cabin quilts, you can use 1/4 inch graph paper and paper piece. When you purchase your graph paper, make certain the lines are the same on both sides. Some papers have 1/5 inch on one side and 1/4 inch on the other. If you cut the seams down to 1/8" it's not good for a "usable quilt". The seams will come apart. I learned this lesson when a small wallhanging accidently got into the washing machine.
