I have been sewing my 120 HST (half square triangle) blocks for step #4. I like using the Angler 2 for this kind of a job. The only thing I don't like about it is when I run out of bobbin thread and have to take it off the machine to get out the bobbin, and then realign everything. I am happy with not having to draw the diagonal lines, and the accuracy is fairly good. I did square up each HST to 3 1/2" to make sure the blocks fit well with the 4 patches.
One block done, 29 more to go!
