The only time you could get in trouble (and I really doubt even then) is if you mass produced something and sold it in quantity. But, morally, it would be nice to print up a 5 x 7 sign saying pattern designed by _____ and original color ideas from store_____. This allows you to credit the person and perhaps lets another quilter start a new project. The exception to this is when you use licensed items. Example would be using disney images on quilts, totes or apparel items for sale. Disney is very diligent about attending large fairs and swap meets looking for their product. But, to make something that is raising money for a church or raffling for a charity is not something they would pursue.
