I love, love Triangulations. It's a software that prints out a paper sheet that will make many, many at a time and they are perfect. No trimming needed. You put your two fabrics, right sides together, lay the printed paper (I use doodle pads, very easy to tear off) on top and pin, then sew. There is also some free online you can use to print out the grid. Most of the basic sizes. Depending on size you can make 24 at a time, but they are the same. I am a scrappy girl so I handled this by organizing a swap for 2" hst, saving 6 for myself I traded the others, making many sets with different fabrics. I have a postage box full of 2" hst after making an Ocean Waves which used 4,000 of them. I am now making 2 1/2" hst for a split nine patch and I am making them with the Easy Angle ruler by Sharon Hulgren. It has that 1/4" built in and works well, but they need to be trimmed. Those that don't make the cut go in the 2" hst box. I try and cut them a bit larger and I'm not losing too many of them. I think Triangulations is the way to go tho.
