Here is a grown-up version of my ombre garland from scrumdilly-do! By grown-up I mean I cut the bottoms a smidge fancier than a kiddo would and stitched the whole thing together instead of stapling. I finally got a bit of crafting in what with being sick and all. Oof!
One color of paint with white added a wee bit as you paint each fold of the paper. After cutting, fold over each strip and scallop it all up before stitching it. You can also use a whole punch and string it up, or maybe some glue or staples even. It doesn't need to be fancy, just happy!
