Or you can cut the width in half which I've done many times. Just sew a double scant quarter inch. Never any issues. As long as all your widths are the same your block may be a little shorter.

I am almost finished with a LC quilt top made with 3 jelly rolls and a fat quarter bundle. It will be a very large queen size and could be bordering on a king. I'm tossed up about adding a border though. The material I want to use are batiks from my stash where I tried to pull ones with colors in them from the top. The top is all solid colors with exception to about 10 blocks that almost look acid washed. Those give it some character (I think).
