I'm beginning to get better at it, but I have to pull out the instruction sheet from Quilters Cache if I haven't done it in awhile. I've never done a complete quilt with it! BTW, the instructions there are easy to understand and follow. I still have trouble getting the right size/shaped piece. I have learned to trim after each piece. Once you start "getting it", the blocks are very crisp and you can make intricate designs easily. It just takes practice!
