Stencils are so fun and I have found that the best ones are the reusable adhesive stencils. I love them because they keep the colors from slipping under and blurring the design!
You can watch a video on how I use them HERE!
Here are some links to where I found some great stencils:
The Mosaic stencils from the video and photo are HERE. I bought the large sheet and cut it up. They have some patterns that have worked well in the past like mushrooms and Christmas trees (they are SOOO cute) but it varies what they have in stock.
Another place for some fun stencils like these Easter ones is evilcakegenius.com

Search for their "Stay put cookie stencils" and they have some 2" ones that work great! Also look for larger ones that you can use partially like snowflakes etc.
The Gold Luster Dust that I use for painting is one I got from The Sunflower Sugar Art
and I love using The Color Solution to mix my dusts into "paint" (one bottle goes a LONG way) but you can also use Vodka or clear extracts.
After using my stencils I wash them with dishsoap and warm water, pat them dry and then lay them flat until they dry completely. I save them on the same backing that they came one and store them in ziplock bags to reuse!
Happy Pucking!
