    Default Triangles and squares.

    I am making a quilt from an older pattern - nine patches set on point. The problem is with the side triangles. The square blocks in the side triangles are 4 inch squares. The instructions say to cut a 6 1/4 inch square and cut into 4 triangles (corner to corner). The long side of the triangle is on the straight of grain and the bias edge is to be matched to the side of the 4 inch square. In my opinion the triangle is much too big. I really have to ease in the length to that 4 inch side and even then it looks wrong. Is there a quilt math wizard out there that could tell me if the instructions are off? It seems like the triangles should be cut from a slightly smaller square. Help. Please.

    Haha you and I are on the same page of our projects today! I posted earlier today "setting on point" so take a look at that. My instr say cut a 3.5 inch square then cross cut twice like big X for setting triangles. The block I am beginning with is 2 inches--so if that is a formula then add 1.5 to how many inches your block is? Maybe make a sample and see if that is a better size than what you did before? Good luck, I hope it all turns out ok for you.

    Here's a chart that might help... http://www.allpeoplequilt.com/sites/...d_trianges.pdf

    http://www.quiltersparadiseesc.com/C...Calculator.php

    It sounds like those are the corner squares for the quilt. The set in triangles should be cut on the diagonal (bias) and just 1 cut.

    Check out the two sites, I found. You'll probably find what you need there.

    I've always cut my set in triangles bigger than needed. The trick is DON'T ease it in. After all your triangles are sewn in and your rows sewn together...then trim off the excess.

    The triangle you start with should be too big and you will trim away excess. Here's a diagram for how to line things up:
