I'm with you on the whole pain of destashing. What I did a month or so ago was sold some yardage here on the Board. The people that bought it were so verbal in their appreciation, it made me feel a little better. I also like the idea of going through and getting rid of what you don't care for anymore. We all go through phases of the things that we love, and someone will see your fabrics and be so glad to have them!
And, I'm sorry, you can't use the "I'm in my 70's" to try and make yourself feel better about getting rid of some stuff. 70 is the new 40!!! Lots of time left. (that's my story, and I'm sticking to it!)
