That is a really fantastic quilt. I don't think any design will take away from the effect. But if you have leftover pieces why not make a sample to try out some options.

Thanks so much for all the help .
I ordered a lot of different grey threads and one each of the clear threads . I,m going to just sit tight and may be try some on a couple my left overs .
Just have to wait for the mail to come in about 2 weeks.
I was good just ordered the thread and a little piece of cotton . LOL
Thanks again
Tom
