The mess of my floss has been the bane of my existance for more years than I can count. I started embroidery when I was about 6-7 years old and have just accumulated threads from projects and thrown them in the top of the boxes or bags. In organising I found sooooo many duplicate colours and the end result was so satisfying.
I think these pics show the importance of keeping your stash and your current project threads organised. Makes it so much easier to find what you’re looking for, easy to incorporate new theads into the stash, and stops you buying thread for new projects you already have.
