Those swirly lines look like my "meandering" I do on my shortarm system. I like them a lot...they cover a lot of ground, and can be made to fit anything. Good work!!!
You could also try selling on Etsy, where a lot of people on this board have sites. Competition out there is extremely high, so....it's really a gamble. Think about it before you spend money on a website and all. You can do charity quilts and write off those supplies as charitable donations. Just get the organization to give you a receipt for whatever the "market value" of the quilt would be.
