In need of advice.

So when I was 13 my mom passed away. A little while ago, someone gave me a baby blanket she made for her son. Little did I know that was my sign as I found out a week later that I was pregnant. Fast forward 3-4 weeks and we discovered it is twins. This blanket is definitely being used, but I want one more for the other. I want something that is hers or something that is representative of her, but I don’t have any of her stuff bc I’ve moved so much since she passed that I lost it all. What can I do? How can I make a blanket for my baby with something of hers or something that commemorates her?
