I read about the Wonder Cut ruler and looked it up. Then I recognized it! I have one and have never used it. I looked up the instructions and am amazed. I'm going to use it now!!

I wonder what other rulers are in the bin. I'll have to go through them and see what else is there.

I have the June Tailor and love it. I cut my squares a little bigger and trim them down.

Tia, do you like it better than the wonder-cut and have you used both? I think the June Tailor ruler is available at joann's and the other one has to be ordered. It's good to know so many members here do cut their squares a little larger and trim to size. I can definitely see the wisdom in doing that...i have never made one in the traditional way that wasn't wonky after pressing, even when certain they are cut perfectly and sewn perfectly--you trim the little corners and the square nearly always requires add'l trimming which decreases the finished size in the end.

I can second this. I almost lost my mind until I read about and purchased "Triangulations". Now I look for things with HST to do, it is no longer an impossible chore, it is FUN.

I don't like paper, so I just draw out a grid of squares and sew up a whole bunch at one. Here's the directions:

They make up fast and perfect.

I also find this is the easiest way to make HST's too.

I actually have Thangles in every size they make, I love them

I prefer to use Tiger Tape for HST's, but sometimes, if the initial square is big, I draw a diagonal line using a ruler and pencil and then sew 1/4" away on both sides.

There is an illustration here:
