If you are making masks or activity packs, Scrapstore is well worth a visit. The up-coming give-away sessions are on Friday 17th and 24th July 10-2pm at the Meadows community centre in Kings Hedges.
Scrapstore collects play-safe waste from businesses and individuals and helps it to be re-purposed rather than going to landfill.
They also have a limited number of free summer activity bags to give away to families containing crafts materials and activity sheets. https://www.facebook.com/camscrapstore/
