There's great DIY-instructions all over, but I guess it's pretty straight-forward: Just dip.
I hope to work on my own dipping-project soon, but am still looking for the right things to dip.
More on that shortly (and on how easy it actually is...).
Meanwhile here's a little dipping inspiration from Etsy handmade:
