Anngel, I feel honored you liked your mystery enough to share. I don't see a problem with this as long as you didn't sell it. LOL
It isn't copyrighted material, but I hope I got some credit for it with your group! Nothing used in my quilt top was original, I just put together blocks that have been around for a billion years.
I truly feel that sharing with others is a way for others to learn. I know I have picked up many many tips on this QB that I never knew before. I am new to quilting, self taught 2-1/2 years ago by what I looked up on the internet. Without all this information available I would have had to take some classes.
