i would check out some things on Pinterest. They usually have good DIY ideas. but people always look up how to make bracelets, tie dyes, if you wanna get really crafty you could make ceremics. Knitting, crocheting, bead animals are cool too. You could do a DIY baking/cooking section as well. Hope this was helpful :)
Get a lot of crayons and put them in little cookie sheets with shapes and cook them so that they melt together. It looks beautiful and stuff.
Go on youtube and check out really popular diy projects and recreate them (don't copy) like don't say the same words, use the same colors and etc. people don't really appreciate copycats on youtube, but you can always make something with your own take on it :) hope this helped :)
Start out with some easy stuff like how to make a crop top, destressed jeans, tube tops, skirt, nail stuff, and makeup stuff.
