You'll need the following (if you choose to do it the way I have, otherwise, mine could just be a seed to help grow your own ideas & you might find other ways/resources):
OML! These cute (I'm sure you or the kiddies would create MUCH cuter!) little gift tags are soooo self-explanatory that, I don't even feel the need to even do step-by-step's, instead I've done it as pictures!
Obviously, once painted (painting isn't a must, it is just my preference. However, I lost patience so I skipped the paint & used glue insteasd), get your glitter and cover the tag/wet area! Tip off any excess & BOOM!!! You have the bottom results.
Add string (coloured or plain) and you are DONE!!! This has got to be theeee' most straight forward DIY in the whole world!
