I have used the Angler 2 in the past, that fits on the bed of my machine, and had fairly good luck but just wondering about trying one of these other methods. What is the method you use or what works best for you. Just curious. Appreciate your help.

    Cut 2 sqs. Different fabrics that go together.
    Put right side together sew 1/4" seam around all 4 sides
    Cut across corners diagonally in a X being precise corner to corner you have 4 half sq triangles

    Well, this "Leave a comment" box wasn't here the last time I tried to post a comment!
    Anyway My thinking on this to answer Carol is that I've never heard of adding a 1/2" strip but here is what I do.
    I take two pieces of fabric and place them right sides together. Then on the wrong side of the lighter fabric you make a grid of squares that are 7/8" larger than the finished size of HST's you require. Then you mark the diagonal lines through all of your squares. Now sew 1/4" on both sides of that line. lastly cut on all of the drawn lines.
    All of this being said I prefer to add a full inch and trim all of my squares. This way I'm sure to have squares that are the right size, and none that are too small. I hate the trimming, but to me in the long run it's worth it.

    I don't understand Modernmillie's idea because all of your finished HST's would have a bias edge and that is usually a no-no. you could cut your squares on point I guess. If you do she didn't tell us what sizes squares to start with to get what size HST's. That information would be helpful.

    I have found that the "rule of thumb" on making half square triangles is cut your squares 7/8" bigger than the size you want. Mark the diagonal line in the center and stitch 1/4" on both sides of center line to create two HST's. If you need a lot of the same type, it's easier to grid out a larger piece of fabric and make many at the same time.
