I agree with the others that $150 is too low. As I hand quilt, I charge 3X material costs and sometimes more depending on the intricacy of the pattern and quilting. Fact of the matter is that you may sit on a product for a really long time that way. I'm sure your MIL appreciates beautiful eye-catchers in her store however. If you look at it that way - and remember to tag the item correctly, and make it known that you are willing to do commissions ( state your parameters here - this pattern, your colors; any pattern , your colors, etc) you will find people who are interested in YOUR work. My items can sit for a long time on my artfire site - but when they do sell, I am one happy lady. Folks who undersell make me very angry. It hurts all of us who might like to make what we are worth! If all else fails - give it to someone who will appreciate it - or keep it for yourself!
