Need snow? Paint yourself a winter wonderland. Daiso sells pearlescent white paint for $2 in a small tube. Use a fine brush, load it up, and let the paint scrape against the edges of your craft project (in this case a party favor box).
Try to make it look like natural snow drift by painting from one direction (so don’t coat every edge).
This triangular party favor box is sold on Etsy, along with other dinner party paper decor. Half-moon shaped flaps are on both ends to allow easy access to your stocking stuffer. Perfectly size for biscotti treats.
