Place the split peas in a bowl large enough to fit your wreath. If you don't have a bowl, put wax paper down on the surface and spread the peas around.
Set the wreath down in the peas and paint on the Mod Podge. Paint a section and sprinkle peas on that area. Keep going until the entire wreath is covered. Let dry for 30 minutes.
Fill in the bare spots by adding Mod Podge and peas in those areas. You might need to go on thicker with the Mod Podge to get the peas to stick. Just don’t add too much – otherwise you’ll get clumping.
Add two final coats of Mod Podge to seal the split peas to the wreath.
Add ribbon and an embellishment to the top to finish, and to hang.
