Hi Eriq: Here is a ton of ideas here on Hometalk:
Here are a bunch of projects https://www.hometalk.com/search/posts?filter=wine%20cork
repurpose a cheap framed print. Remove the print and glass. Slice the corks lengthwise in half. Stick the corks to the timber base, using a hot glue gun. The pattern can be straight or varied ( to your imagination). Stick notes etc with appropriate notice board pins. Also you could make a frame from moulded timber on a particle board base. They look great.
Hi Eriq - We made this super cute flag with leftover corks. It was even featured on Hometalk! You can see the DIY here and hope this helps with some inspiration. Hugs, Holly
