I read somewhere on the site recently where the ladies were talking about using a spray glue instead of pinning when sandwiching the front, batting and back before quilting. I am not finding that thread of discussion now.
I have just finished the top of a wall hanging "Mexican Star". I have never quilted anything myself, but sent it out and paid to have it done. I now want to try to do it myself.
Is it good to use the spray glue to keep the batting and the front and back together?
I hope this picture gets posted. Also, what would you suggest for a simple quilting of this.
