First, if you sell your quilts, you absolutely must account for your time; it is just as valuable as any of the supplies you need to make a quilt.
I wouldn't worry about what to do with the quilts you make if you're hesitant to give them away or donate them. Oftentimes, the joy is in creating it.
My quilts are scattered around the house, hung on walls, thrown over sofa backs, folded and ready on the recliner for nap time. We love living among them even if they don't exactly match the rest of the decor.
