Jelly Roll using the binding tool

[rebeccas-sewing]

I'm pretty sure 4 jelly rolls should do it. Did some math as follows: For a generous size queen quilt with 16" drop on 3 sides:
40 jelly roll strips times 2" (this excludes seam allowances) = 80"
80"x 39.5" (WOF excluding selvage) = 3,160 sq. in.
92" x 96" = 8,832 sq. in. (size of a generous queen quilt that includes 16" drop on 3 sides)
Dividing 8,832 sq. in. (quilt size) by 3,160 sq. in. (jelly roll size) = 2.79 which rounds up to 3 jelly rolls

I'm pretty sure this is right based on a queen size mattress that measures 60" wide x 80" long
(I had my math genius husband double-check my figures)

3 jelly rolls would do it but that's cutting it really close. If it was me I'd buy 4.

My calculations only include a drop length on three sides of the bed. If you're planning to tuck the pillows under the quilt you should probably get 5 jelly rolls.

I have learned the hard way that it is better to have too much than not enough.
