I agree. I love thrift stores for finding fabric. It is always a little like Christmas when I find some. Often it is vintage stuff that brings back memories from when my grown kids were young and I was just learning to sew. Sometimes it is newer stuff.
The one thing that makes me sad is when I find beautiful work that someone put heart and soul into, that was donated to a TS. My husband says I am a "rescuer" because I have to bring them home. I repurpose the items I find and that makes me happy again! lol
Several months ago I found two gorgeous wall hangings and several table runners that were very recently made, just guessing by the fabric used, and I bought them ALL for the ridiculous price of $8. The wall hangings are displayed proudly on my walls, and one table runner is in use, the other three I gifted to a young woman who was moving into her first apartment.
I celebrate the person who made them every time I look at them. They bring me much joy.
