1. One choice is to rip it out which is always easier said than done when ripping out machine quilting.
2. I could cover it with different fabric. Hmm, I will need to ponder this one a bit more and do some digging through my stash.
3. I could try and go with what I started and see if I can salvage. One is usually hopeful things will work out in the end but it could end up with something even worse.
