I've seen that quilt room...upstairs. About 6 years ago and the 15 years prior to that.
The 15 minute timer was the method I chose. If I cared enough to buy it, then I cared enough to be a good steward of it. and being on the timer makes you work fast, no getting side tracked by catalogs, new ideas for wannamakeit...
I've maintained a lovely room since then by putting things away after I was finished with them.
If something comes in something has to go out (flylady rule)
Went on the fabric wagon (that was back in 2001)
Leave my project when finished for the day in a way that I can come in, sit down, and go to work on it.
teach myself a finished top is ok, people won't send finished tops to the dump, but they will send UFO's by the dozens.
I love my quilt room, I wish the same for you.
