A jelly roll is 2 1/2 strips, and they usually either have 40 or 42 WOF strips, or about 3 yards.
Your pattern calls for 1 1/2 strips, so you'd have an extreme amount of waste, plus, you get one or two strips of each fabric in a collection in a jelly roll, so even if you made that quilt, you wouldn't be able to get the coloration that is in the pattern. (It's a nice pattern, go for yardage for it.
If you search for jelly roll patterns, you should find many options, a 1600 quilt is a very easy pattern for a jelly roll. I also like to look on Moda Bakeshop for precut patterns.
