Every Year, when Izuku's birthday rolls around, Katsuki convinces his parents that he needs to gift the nerd the newest, limited edition hero merch; whatever's All Might themed. They always agree, because they're just happy to sew that their emotionally consitipated, egotistical little gremlin cares so much about someone, even if he's always brushing it off as 'nothing' or 'no big deal' or whatever other excuse he can come up with.
Izuku tries his best to pay back such a big gesture, but he never can, due to his financial situation and the fact that his mother has to work two jobs just to be able to afford rent and groceries. Even with his own part time job, that put him at risk of being kicked out of school if anyone found out and snitched on him, he can still barely afford even just a basic All Might figure from the discount bin (which are still pretty pricey, due to the #1 Hero's popularity).
But what he can afford is yarn. It sparks the idea in his head to take up the hobby of crocheting, and make some unique All Might themed stuff for Katsuki, stuff you wouldn't be able to buy it the store or online. Plus, it would give him a creative outlet and something to do to help relax.
So he buys all the yarn and other tools he'll need with his savings and rushes home to get started. He grabs an empty notebook, hops on the computer and begins his search. He looks up beginner tutorials, pattern ideas, he practices and pours his heart into making all kinds of handmade gifts to repay Kaachan's expensive gifts to him over the years. His mother comes home and is surprised to him her son buried to his knees in yarn, furiously attempting to crochet an All Might doll.
By the time Katsuki's birthday rolls around, Izuku is pretty pleased with his handiwork. On the bed, he has arranged all the item's he'd spent the last few months painstakingly crafting in whatever spare time he could get. They were all wrapped up nice and neat, and to say his hand were sore and cramped would be an understatement. His mom helps him get everything gathered up, and they make their way to the Bakugou household.
Mitsuki greets them, and everyone's shock to see Izuku and Inko hauling in at least 20 wrapped gifts. How much did all that cost them?!? Even Katsuki is more than a little stunned by the sheer amount of gifts brought in by the smiling nerd and Auntie Inko; it was probably more gifts than he'd ever given Izuku. It made him feel a little guilty. But the real weight of his emotions wouldn't hit him until he started opening all those presents.
Instead of the expensive store bought collectibles he'd expect would have seriously tightened their budget to be able to afford, he found the unique, one-of-a-kind, lovingly crafted items that the nerdy little Deku had spent so much time and effort on. Each gift that was labeled 'from Deku' on its, was just another little All Might themed yarn craft. Katsuki could only stare in utter disbelief at all of them. A variety of little plush dolls, a couple blankets, a scarf and gloves, hell, even a while goddamned sweater; and that one wasn't even All Might themed! It was made using colors Katsuki had expressed wanting to use in his own hero costume. Orange and green and black, woven together is a tasteful pattern that was sure to suit the explosive teen well.
Before he even realized it, he had tears in his eyes as he pulled Izuku into a tight hug. The idea that somebody, anybody, much less Izuku whom he treated so horribly, would even bother to handmake him anything at all... Well, he was absolutely touched. These were things he was going to be treasuring for the rest of his life. Even if he ended up outgrowing that beautiful sweater, he'd never throw it out. Izuku was just glad his friend appreciated all his hard work...
A/N: I'm crocheting a belated wedding gift for a colleague and had this idea strike me. I think its sweet, and handmade gifts can often hold a lot more sentimental value to the people they're given to. So the idea of Deku learning to crochet and making things for Bakugou to treasure for the rest of his life just makes me happy.
