I bought a Quilt in a Day 4 1/2" Triangle square up ruler that allows me to make HST from 1/2" to 4". I can make 8 at a time and it is so easy and accurate. I love it and I can't imagine making all of these blocks without it. I joined in June and I have finished 2 June blocks and the bonus block. I made the January block and I have my February and July patterns and fabric on my cutting table. I only wish I had a maid to clean the house so I could spend more time quilting.
