There were some really good comments on the "Perfect Jelly Roll" thread (The "Perfect" Jelly Roll) about how hard it was to see what's actually in the jelly roll. And while if you're shopping in person, you can sort of peek to see what fabrics are in there, short of unpackaging or unrolling it, you still don't really have a good idea of what you're working with.
And if you're buying online, it's probably even harder, because you can't "peek".
Here are three pictures of "jelly roll"/ strip bundles. The pictures are all from the manufacturers' websites (Moda, Robert Kaufman, and Timeless Treasures). You really can't see very well what is in there.
The fourth picture is a stack of bolts destined to be cut into strips.
My question is whether seeing a picture of the bolts would be helpful. The width of the bolts (when viewed on edge) is roughly the size of the strips, and if you were shopping in person chances are that you also would be stacking up the bolts to see how well the fabrics play with each other.
What do you think?
