Yes, I was reading that on one of the threads on here. We had a lady come from one of the local shops in our area and she said to use a stretch fabric needle on batiks, which kinda puzzled me. I will try to purchase some silicone spray and see if she will use it on her fabric, she is kinda picky about her quilting and quilt work.
Thank you for your answer...I was looking at the size 18 to use.
