Quilt in a Day 6-1/2-Inch by 6-1/2-Inch Triangle Square Up Ruler (2010)

I’m working on a HST quilt right now and bought this. It works quite well and I blew through 100+ blocks in no time last night while listening to an audiobook. It makes it easy to trim the blocks before they are opened. It’s still manual, I know, but you’ll get better points. https://a.co/d/0i84YuV7
