    I am making a quilt, and setting the blocks on point, so am going to do setting triangles. I already bought the material, and am double and triple checking myself before beginning to cut everything.

    I found this site: http://www.quiltville.com/onpointmath.shtml to calculate the size of squares to make, to cut down for triangles. My problem is, doing it this way, I think I come up one inch short (but of course have all kinds of leeway at the side). The 2 squares would have to overlap.

    So, I wondered if instead of making a 16 1/2" square, then cutting in into 4 to make the side triangles, if I could make some strip and cut it into 2, so I could get 2 part side by side? Know what I mean?

    My pieced block is 22" square, which means the corner triangle is 16 1/2" (rounded up), and the side triangles would be 32 1/2".

    So, what would be the size of the half triangles if I did it as the pic on the right shows?

    The outside edges of your setting triangles need to be on the straight grain of the fabric. As I understand your diagram your second option puts them on the diagonal.

    Good point, didn't think about that! Uggh!! What do I do?

    Could I do 4 triangles, cut seperately? Put the flat side parallell to the sevledge? Then the 2 sides would be both bias? How tall and wide would the triangle be?

    The place I bought the fabric is not in my town, and I thought I was buying plenty. But now, I think the 16 1/2" square and the 32 1/2" square equals one inch more than the yard and a half fabric I bought.

    ??16 1/2 + 32 1/2 = 49; a yard and a half is 54 inches. It sounds like you have plenty.

    You all would be right IF...

    I had not forgotten about the center square! Uggh!

    I think when I typed the message yesterday, it had just been too long of a day!

    For some reason, I was coming up with 48" instead of 54" for a yard and a half.

    Well, since I have now remembered the center square, I will need to go shopping anyway.

    Don't you hate days when your brain stops working? Thanks for your help everyone. I knew I could depend on you, too bad I couldn't depend on me! LOL

    ahh, grammy! If you only knew how many times I thought I read the directions! LOL
    You know? I always say that you really don't know me until you see what I do when I hit my thumb with a hammer ... and, that was the first thing I thought when I saw your newest posting ...
    When push came to shove, you knew who to get encouragement from, and you knew how to fix the problem, so it wasn't really a problem ... you just got a chance to see what the Quilting Board can do for you!

    I knew I could depend on everyone here. You are all always so helpful to everyone! I am having my hubby check all my cutting plans to be sure I have allowed enough seam allowance, and that each cut is big enough for the template, and that the total yardages does indeed add up! Thanks for the encouragement! Have a great day, all.

    Here is a site that might help:

    http://www.quiltbug.com/Articles/on-point.htm

    It is instructions on setting on-point and cutting instructions.
