I have sold things on Ebay for over 10 years. Rules continually change, and the fees have gone up over time. For a person just starting, I would recommend buying a few things on Ebay first, so that you can establish a "feedback" rating and get the hang of how things work.
Several years ago I sold a few quilts on Ebay for a friend. Because people cannot see the quality of workmanship from a picture of the whole quilt, it is advisable to take many close up pictures of the stitches, corners, etc. Imagine the risk a buyer has in buying a quilt sight unseen. I would hesitate to do it myself.
On the other hand, I have sold many vintage quilt tops successfully on Ebay. Again, close-up pictures are a must, and definitely get one of the back side, so that people can see the workmanship.
Best wishes on your venture!
