16 tumblers wide (54') by 17 tumblers rows (73.5")
By the bolt JoAnn's bleached 100% cotton muslin 60" wide was the inside layer - between a pieced cotton top - and Robert Kaufman's cozy cotton flannel. A better feel than just with cotton top & flannel back.
Flannel back, muslin and fabric was pre-washed since they were all 1/2 yards to start.
The quilting lines followed the tumbler shape. Gutterman sew all thread for the top and Isacord 40# 100% polyester white for bottom bobbin worked great with a walking foot.
