Going for a king size? No big deal! (I can't imagine a king sized any quilt as my arms just hold up to the battle with that much fabric anymore!!
)
Want just a baby/crib size? Gotcha covered! (More my speed, LOL!
)
This resource has done all the math you will ever want, to determine the number strips/rolls you will need to make any size jelly roll race quilt your little heart desires!
