I would take it back also.I'd be kind, but I'd take it back. I do embroidery A LOT and I make quilts and wall hanginGs(haven't ACTUALLY FINISHED A QUILT YET)But I do know to get those puckers out you have to spray it with water and PRESS and I mean PRESS over and over until they are gone.And it may be the tension was to tight.BoY that is SO bad.I sure hope the best for you.Please let us know how it all turns out for you Ok?
