Simple DIY! The dollar store oftentimes has gorgeous flowers, thrift stores always have vintage frames, and for those who want something a little sturdier than cardboard for the letter, Michaels or JoAnn's carry wooden letters in all sizes!
You make these by dipping (or dredging) yard through a corn starch/glue mix, then wrapping it around a balloon coated with Vaseline so the glue doesn't stick. Once the yarn and glue mixer is dry, pop the balloon for this whimsical DIY lantern! I heard you can also spray paint it after it fully dries for a colorful effect.
