Been there - done that -
Some of us jumped/plunged into quilting big-time - we may have spent thousands and thousands of dollars on equipment and supplies
And then comes a day when we just don't care about it any more.
For whatever reason - health, something else is more interesting, family issues - all this stuff is around that is no longer useful, or interesting.
Why should one feel guilty about moving on? One can take a trip/vacation - spend the money - when the trip is over - the money is gone and only the memories remain (unless you are a photographer or buyer of zillions of souvenirs).
The point of this post is - if one has lost interest in quilting (or whatever hobby) - in most cases, it's okay to let it go.
IMO.
