So a week or so ago, I posted the back for my latest quilt and was asked if I figured out the math myself. Yes, and I guess I usually do. At any rate, that led to a few commenters asking for help with quilt math. I knew several of my quilting friends had already written really fine posts on the topic, so rather than start from scratch, I rounded some up. There's lots of good info here, so hopefully you'll find something that can be helpful!
- Jess/Elven Garden Quilts and Leanne/she can quilt ran a Decipher Your Quilt series a while back, and it's a great resource. You'll find posts on accurate cutting and 1/4" seams, math for a variety of block types, and more.
- Katy/The Littlest Thistle has several Quilt Making Basics posts on the topics of Half Square Triangles, Flocks of Geese, and Quarter Square Triangles. In each, there are really helpful charts showing what size fabric you'll need for a variety of sizes of blocks. These are a gold mine.
- And yes, another post on HSTs is my own tutorial for Big Batch HSTs if you're needing to make alot with the same two fabrics.
- If you're curious how many blocks you need to make a certain size quilt, see how to calculate quilt measurements by Amanda Jean/crazy mom quilts. She also pointed to a Fabric Calculator, which is pretty amazing.
- Measure Twice: Formulas for Borders, Backs, and Bindings is a really helpful post by Sherri McConnell on Craftsy.
- And something you might not use often but is really helpful when you do is Lindsay Connor's On Point Quilting: Tips and Calculations, also on Craftsy.
