When I have free time, I like to do crafts with friends.
What kind of crafts do you enjoy?
I like to make bead bracelet or necklace. I also like knitting. Anything DIY is fun.
An important tip for knitting and crochet is to determine the yardage for unlabled string and yarn.
You really sound like an expert about knitting. I always have problem to estimate how much yarn to buy for a project. To be safe, I usually buy more, sometimes too much.
Three weird things people have knitted is a hot air balloon, overalls, and lampshades.
I have never heard about knitting hot air balloon. How could that work? I mean knitting patterns cannot hold air.
I don't have the answer to that question, but look it up on Buzzfeed.
I have to check this out. Or maybe they just knit the out protecting layer of the hot air balloon. Do you like crafting? 
Crafting is a great activity.  One craft that sounds fun is woodworking or miniature making, but it requires a lot of tools. 
Woodworking is really creative and needs tools and skills. Making things from clay is also fun and creative.
