I have loved reading through the responses here...some are really terrific!
If you want to sell your quilts or not that is totally up to you.
I have been learing to quilt in my local quilt shop, with Claudina who has made hundreds of quilts and owns the shop. She told me she still gets "advice" on quiltmaking or design. I asked her what she did or said about it. Her reply was if she wanted to keep the peace she ignored it... if she didn't care she asked "How many quilts have you made today???"
Great mentor and friend!!! ;-D
