I've been having some problems with the previous carpenters stars' points not quite matching. This isn't something that really bothered me, as I am really just a process quilter; not a product one, but I thought I might poke around to see what I could do to make things (somewhat) better. I had been making my HSTs by doing the usual draw the diagonal line on a square fabric and sewing 1/4" from the line, but I had seen some quilters use a larger square to make 4 HSTs at once.
Here's one great site that explains this, and another, and here's the math behind it, from the 2nd link / pinterest:
Since I was wondering if the bias edges made a difference, I cut my squares on the bias, seamed around them, and then cut my HSTs so that they would be on the grain / against the grain, not on the bias.
Here's the resulting quilt, which has much better points than each of the other Carpenter's Square ones. Now I just need to sort out who I'm going to give this to!
