Fabric offcuts or pieces (West Kensington W14)

I am running a community project based in libraries across London offering FREE creative workshops for women experiencing menopause. I am looking for offcuts or oddments of fabric to be used in our making. I am particularly looking for plain fabric to write on, but any type would be accepted for patch working.

If you are interested in the project please email hello@invisiblevisibleproject.com

Thank you :-)
