All the fabrics for my clothing design business come from deadstock and end of roll from local fabric shops and small craft hubs. I always save the off cuts and now turn them into home decor and jewellery items meaning I don't put anything into the bin.
Here's an example of how I use even the smallest lengths of fabric to make something with a whole life ahead of it and stop me adding to the landfill problem.

I also make braided coasters and fabric bookmarks and its really helped me expand my business. Enjoy and I hope it can inspire some of you too!
