I agree, tuck the edge of a label into the worst fold and stitch it down then scatter other sayings or info into or over any other bad spots!

I just realize that my quilt has wrinkles just like me. Then next time I make sure that my backing is smooth before I quilt Happens to all of us at one time or another

Sorry but I think you should take out the quilting. since this is a challenge quilt and will be put in a show then it needs to be almost perfect with no noticible flaws such as you have. also you might really be embarrassed to show others this is your best work. If you are just going to keep the quilt then you may not want to rip the quilting out. However since you asked us then it sounds like it is really bothering you. Nothing is perfect but there are degree of imperfection.

Here is the finished backing. I ended up "hemming" just the worst small section that had a 1/4" fold and left the rest alone. The front turned out okay, and that is really the only part that matters for this quilt since it's not going to be judged, just displayed.

Here is a thread on the front if you're interested in seeing that: http://www.quiltingboard.com/picture...e-t235999.html

I'm proud of myself for not pointing out the disappointing back in that thread even though I wanted to confess my sins. ;) I don't know why we all so desperately want to point out our quilt's flaws.

Can you fold and stitch down so it is not seen.

Look at Post No. 34...

Yea! It looks great to me and it is finished!!

I agree with both snipforfun and Peckish. Hopefully, maybe washing will give the quilt back a more crinkled look. I was taught back in the 80s, when machine quilting, use a busy print on the back so that mistakes wouldn't be as visible as with a light neutral print. We all learn from our mistakes. I give you a big thumbs up for trying something different with basting the quilt. I always check that the fabric is smooth by running my hand lightly over the back of the quilt before it goes under the needle.
