I have a headcanon that Steve due to boredom and alot of time by himself in bed developed a knack for sewing. He mended things his Ma needed done while she was off at work, he sewed up his own clothes when they got ripped and frayed.
Eventually, Steve got good enough at it that Steve would start mending Bucky's clothes, and then all of his sisters too. When they needed something done (and they didn't want Mom to know) they came to Steve.
Steve made himself clothes once or twice, but fabric was expensive so he mostly stuck to mending here and there. He sometimes even dabbled into embroidery, making his Ma a nice flower pattern on one of their tea towels. But he never got very far with it. It was a simple, time wasting hobby.
It was a good skill to have during the war. The Howlies regularly needed tune ups on their uniforms, and Steve was usually grateful for the distraction. It was also good for when bullets and knives and shrapnel sliced into skin. It was good when he could cut off the blood flowing from Moritas thigh, or Gabes arm, or Dugans leg. It was good when it helped his friends from bleeding out in the middle of a damp forest or snow capped mountain.
Steve still mends his own clothes, he even bought a brand new sewing kit filled with 10 different colors and a pack of 16 different sewing needles. He never dreamed of having all those fancy spools as a kid, but now he can pick between violet, to pink, to green, to red. He could use whichever he liked.
He started embroidering again. No one ever saw, it was just his. His own private little thing that he could indulge and focus on for hours and hours. All to himself.
