I like to try new things, but not always with good results (sometimes operator error). I was using pins to baste my quilt sandwich when I first started quilting, but tried the spray basting after discovery. I was less than thrilled with the results, but it was my fault for overspraying. After getting the spraying process down pat, I was sure that there was nothing else I would use. WRONG! Then I discovered glue basting and quickly decided that it was fast, easy, and super cheap....all while doing the job of keeping the layers together. But...spray still has its' own benefits of being very fast and no drying required.
Soooo, I guess my point is that lots of techniques, tools, battings and fabrics each have their own benefits and spot in my quilting life....but maybe not in the quilter down the street....to each his own! But I do love all the quilters here on the board who share their ideas and skills.
