    Quick math question

    I'm planning on making something using both squares and half-square triangle units. If the squares I'm cutting are 5 1/2 inches square, then to make the half-square triangle units I want the squares for that to be 5 7/8, draw a line up the middle, sew 1/4inch next to the line then cut on the line; correct?

    I would, too.

    I usually don't need to trim much - maybe 1/16 of an inch at the most.

    When I use the plus 7/8 instead of plus 1 inch - my HST units almost always end up skimpy.

    I think it's because when I cut around a template, there is a tiny bit of fabric added - when cutting squares in half - that extra isn't there.

    I like that pattern. Looks nice and complicated, but relatively simple to make. One more block to add to my to-do list!

    Joan -- I always add a full 1/2" instead of the 3/8" when I cut squares for HST. That way I can trim down the blocks, make sure the lines are perfectly in the points and if either my cutting or sewing is a bit off I have the extra.

    I agree...I add the inch to whatever I want the finished size to be and then trim. Makes for a much better block - at least for me. Not sure if it's my cutting or my sewing that is apparently not too accurate so I err on the side of caution. I can afford to give up an eighth of an inch of fabric.

    I would too - I always add a full inch then trim perfectly square.

    As I have aged, I now get confused with trying to figure the math part of quilting. I just try making a sample using scraps until I get it right.
