One of my favorite things to look for on Etsy are craft kits. Just about any kind of craft you're interested in, but don't know where to start has a kit put together by another maker. I like them much better than the kits you find at art stores. Mostly those kits are geared towards kids and have shoddy supplies. These kits are for the most part put together from whatever supplies that maker would want to use. Plus you get their first hand knowledge in a project or two with it.
This screen printing kit is actually in my etsy shop. A lot of the free stencils I offer on my blog work well with it too.
This Frame Loom Weaving Kit from Hello Chiqui is an amazing starter kit. It comes with everything you need, and each piece is made beautifully.
If you've ever wanted to try your hand at the urban homesteading skill of soap making, this Cold Process Soap Kit from Wild Herb Soap Co looks great.
The Embroidered Doll Kits from Kiriki Press are adorable and would be a great way to practice your embroidery.
JPants has so many terrarium supplies, but my favorite are the complete kits. Everything is packaged beautifully and comes with tiny amounts of everything you need. This Desktop Terrarium Kit looks really fun.
