If you have limited DIY skills, the dining room is a great place to start. Projects like tablecloths, napkins, and placemats only require very basic sewing skills, and DIY centerpieces are easy to make from things like bottles and tea tins. Click below for a few ideas we found on Etsy...
These Felt Placemats from FilzFelt are a simple, no-sew project.
Placemats, napkins and coasters are easy to sew, and don't require a lot of skill to make. This lovely set is from Margot Bianca.
These tablecloths from Pata Pria are hand-printed. Try your own hand-printing with Lena Corwin's guide.
Sometimes DIY just means repurposing something you already own. Tea towels (like this LAVA print from Skinny Laminx) make great placemats and napkins.
We love this idea from GirlsCanTell: design a set of coasters to be used together or separately, like puzzle pieces that fit together to form placemats and trivets for the table.
