I'm only a year behind you and my solution that that question is to make use of more of my stash...now that I've built it up.
I have not stopped buying fabric I like, I'm just more selective....otherwise called "picky"!
Considering that I have a wealth of quilt tops stacked up waiting their turn to be finished, I guess I haven't slowed down.
What's age but a number????
There are days when I wake up and think that my mental state (I'd say brain, but I've demonstrated the lack of one all too often) moved into a biological shell (aka bidy) that is more antiquated :P
