I have used these to make sleeves for my to go coffee cups. I’ve also used these to make potholders. Or a long thin belt that I’ve used to tie to each end of my yoga mat so I can sling it over my shoulder to carry.
Also this book has plenty of ideas
Yay! Knitting or crocheting?
Either way, most craft stores sell a beginner's kit sort of thing that's really helpful. Oh, and it's easiest to learn with solid colored yarn at first so you can see your stitches. All the fancy variegated ones are awesome, but not for starting.
I can't knit to save my life, I can only offer tips for crocheting. I'd suggest starting with a dishcloth (Ravelry has TONS of easy patterns), because you just do the same stitch back and forth...so it helps you to practice and get to an even tension. Oh, and this book seriously helped me. It has projects for super-easy beginning stuff up to more complicated things once you know what you're doing better.
I love to talk way too much about crocheting :)
If you want to do knitting, all I can say is that beginner kit. It helped me, I just don't like it as much as crocheting so I didn't move beyond that kit.
