But it'll take you no time and you already have the supplies!
Sigh...
I knit (and now I crochet too, yay!) and I'm somewhat good at it. I knit a LOT because it relaxes me, makes the kids happy and I like the compliments it gets me. I know, I'm vain like that!

Sadly it is mostly my parents and in-laws that are terrible at the "You should make X for me for free!" and though my mom will proudly wear anything I make her, I have yet to see my MIL wear the gloves I made her. Then my FIL insists I should make things to sell, but shouldn't charge more than 5-10$ for anything because it's cheaper at Walmart...
I do knit for others, mostly hats for the local hospital where DD2 was born because the nurses were just adorable and they kept saying how sorry they were that they had to reuse hats instead of giving them because they had so few. I happened to have a dozen at home when DD2 was born so I had my mom bring them out when they came to visit and the nurses were overjoyed. Made me feel so important, I swear it kept postpartum depression away!
I also knit birthday gifts for DD1's friends, I mostly make either princesses or superheroes finger puppets and they are a big hit! I've had one woman ask me if I could teach her to make them and she just couldn't get the knitting part so I made the bodies for her and taught her to do the hair and faces. She kept wanting to push money at me, but I declined because I figure I can't really ask for what it's really worth (time and all... I shudder at the 2-300$ finger puppets!), so she baked me a dozen cake pops!
She's also in charge of the Christmas baskets the community puts together for people who have fallen on hard times and she told me that they would take anything I make and include it in the baskets. It was great to hear because I often have so much fun with a pattern that I make too many or I have to stop myself because my kids don't want 5 of the same thing.
Another couple of moms have asked if they could buy a set from me, but I tell them I don't take commissions, but since I enjoy making them so much I can make them a set in my spare time. I have yet to meet someone who will insist or be pushy about it, I guess I'm lucky!
Once I had a mom ask me my price for crocheted penguin hats because I had made one for her kid (DD1's best friend) and quoted her a very reasonable 40$. She was thrilled, it was sooooo cheap! She had dozens of people wanting to put in an order and she would pass my info along.
Not one call.
So I'd rather knit for myself, my kids and charity because it makes me feel like my work is appreciated!
