They're pretty lovely boots and you brought them back to life again. I have one of same color but made of suede.
Oh, seems like I'm not the only one who likes keeping seemingly useless things as I often feel they might come in handy some day. I learnt it from old man, lol. He sure knows how to recycle and up-cycle too.
You're right. There's this sense of satisfaction and happiness that come with knowing that you can take care of things or repair things around the house.
