    Re: Half Square Triangles

    Are you pressing vs. ironing? I.e., don't move your iron back & forth over the fabric, just press down in place. Using steam or no steam? (Everyone has their preference re: steam.) When working on the bias, one has to be very careful to not stretch the fabric. My favorite way to do the HSTs is to mark the diagonal line on back of the lt. colored fabric, place the squares RST, sew down either side of the line, cut in half, press, then square up. I make my HSTs 5/8" larger than the desired size to allow "wiggle room". I'd rather trim off 1/8" than have the block be a little too small on one side. I get better accuracy this way. JCY

    Maybe it's me, but when I do HST this way, it is extremely difficult for me to keep everything square and "non-wavy". Another quilter said it was due to all the triangles being cut on the bias, and thus are not as strong or something to that effect. I wasted so much of my beautiful fabric and was not at all pleased with the results. Any short cut or time saved doing it the "easy way" was lost trying fruitlessly in trying to get everything squared up and laying flat. Am I doing something wrong?

    The larger the beginning squares, sewing 1/4" all the way around, the more difficult it is for all 4 pinwheels to come out equal & accurate. In making the Disappearing Pinwheel #2, Churn Dash, I had problems with the 2 layers of fabric shifting (even though they were well pinned) during the sewing. I was using 12.5" for my squares. I gave up after a couple blocks & made the pinwheels using HSTs the reg. way so they'd measure 8.5", sewed them together for the pinwheel portion of the block, then proceeded to cutting it into the 9 pcs., which were 5.5" square. Better accuracy & less frustration. I'm now on the last block of 9. I plan to sew a border on the top & bottom so the baby quilt will be rectangular, not square. JCY

    Great reference, Blondie!
    When dealing with HST's, I square off to the most smallest, if that makes sense.
    Unless it's a complete piglet, and moved off to the side....

    Re: Half Square Triangles

    I can tell you what I have done. I use fat quarters (18 by 21) and cut it into four squares - 9" by 9"
    Then I sew two different squares together, all around. That leaves 9 - 0.5 = 8.5 inches inside the four seams, assuming the 1/4 seam is correct
    The edge of the finished HST will be 1.414 times 8.5 = 12" (almost)

    So whatever size square you start with, subtract 1/2" from that. Then multiply that by 1.4 and you should get the side of the HST block. You may want to start with a bit extra so that you can account for bias. Alternatively, starch the dickens out of it before cutting. Happy HSTs to you!!!

    Half Square Triangles

    Hi this is redbird....first time on a forum! I have a question if anyone can tell me I would appreciate it. When making half square triangles using the square and sewing around the edges and then cutting into 4 pieces to make 4 half squares....how big should the square be? Is there a formula to making different size blocks? Thank You!
Working...
