Thank you all so much for your tips and help! I don't have a dryer (there also are no laundromats where I live) and I usually dry laundry on a clothesline, so I wasn't aware that this is not a good idea for a quilt... (especially not after having seen so many beautiful quilt pictures online of quilts hanging on clotheslines
). I would call my quilt "well constructed" (there's ¼ inch seam allowance on every hexagon and although it's entirely hand stitched I believe that my needle work is not too bad), so I hope it will endure being washed once in a while!
