I sewed it with a 1/4 inch seam. I think what happened is just some of the jelly roll strips were starting to fray without my noticing and I maybe got too close to them in the first place? I can see where the gaps are that that is what happened but it only happened in a few spots so i'm assuming that is what happened.
I don't have any more of the fabric to cover it so I would either need to just use different fabric or stitch over/around it somehow to fix the problems without it being super obvious that I messed up!
