Ethyl, if you can't locate the replacement fabric, I really hope that you will make the effort to find something else that you like and go ahead and finish your project! Make it your own design!

I use a site called "quiltshops.com" to find misc fabric that I did not buy enough of. The site represents over 200 shops that are trying to get rid of (?) parts of collections that they have not sold. Most is on sale. Good luck !
Unfortunately, I did not handle the setting triangles correctly and need to redo them - or something. I tried to purchase or find fabric to completely reset the triangles - but no luck.
Does any one have some scrap pieces left that I might locate?
