I finished my tumbler quilt! See how the design kind of looks like a drinking glass shape? When I decided to make this quilt, I searched online for a template to cut the tumbler blocks. No joy. But I did find super simple instructions for making a template using the cardboard backing from the charm squares packs at Moda Bake Shop. (Thankfully I was using three packs of charms so I had three cardboard pieces. They cut as easily as the fabric and I was zipping right along!)
This is my fourth quilt, and I keep finding myself preferring the backs. You know, the side that didn’t take all that work cutting and piecing and pressing, and I keep liking it better anyway.
I may need to make a very plain quilt to keep for myself.
Fabrics are Bliss by Moda.

soo cute!!
Thank you! I really like the way the tumbler shapes seem to give it a sense of motion. I’ll end up making another tumbler quilt sometime.
you said three packs of charms equals a lap quilt? i’m trying to estimate how many charms i’d need for a twin sized quilt.
Hi, Laurel! Charm squares are 5″ square, so if you use a quarter inch seam allowance your finished squares will each be 4.5″ squares — less if you trim more off to make tumbler blocks. But I still wasn’t sure how many you’d need for a twin quilt, so I did a little searching and found this post for you: http://crazymomquilts.blogspot.com/2009/12/how-to-calculate-quilt-measurements.html Lots of helpful info there! According to Crazy Mom Quilts, you’ll need 280 charm squares.
