Scraps

During my time away from my studio, I learned a few things that I wanted to try.
I found this Youtube video, Scrap Projects by Robin. She uses an adding machine tape roll to make a strip of scraps. Using the strip of paper makes it easier to sew on strips of any size. The strips can be used in borders, an X-quilt, and other projects. Robin also has videos on how she uses her strips. I particularly like the video she has on making an X-quilt with these strips.
I had a bag of odd-shaped strips that somehow survived the time I purged my stash bins about a month ago. I had the bag ready to throw out, since I thought that nothing could be done with these small pieces.
I decided to give Robin’s tape roll technique a try. Instead of keeping the roll intact as she suggests, I cut off a yard of the roll. My scraps were not as organized as Robin had hers. Robin had a bin of pieces ready to sew on. Because of my messy bin, I kept having to start and stop. I also did not want to spend too much time on this today. Cutting off a yard of the roll made it easier for me.
I am happy with the results. I don’t think I am going to go back and try to sew the small pieces in this junk bag. My plan is to start setting pieces aside in a more organized manner as I cut fabric for new projects. I can add a few strips each time I work on another project. It might be nice to have a strip on hand ready to use for scrappy projects.

This is what the strip looked like before I trimmed the edges.

Now, here is my question.
When does one stop saving pieces of fabric?
After trimming off the edges of the strip, I was left with more smaller pieces.

Robin has some suggestions for using the remaining pieces. I have also seen other videos on how to use every bit of scrap.
There has to be a stopping point, right?
Should these all be donated or thrown away?
Or should they be kept to make another project?
I tend to get tired of using the same fabric more than a few times.
I know this is an individual choice, but I would love to hear opinions.
