A crochet baby blanket will be quickly mastered, just make a granny square- plenty of tutorials on u tube and keep going until it’s the size you want.
Baby wool makes a lovely soft blanket, double knit using a 4mm hook.
If you have a flower loom you can make some to decorate it or make some bows with satin ribbon.
Give it a go,I’m sure it will become a treasured gift for your new grandchild.
