You can yarn bomb with crochet with knitting, old blankets or jumpers. As long as it’s colourful and fun and done with care yarn bombing will spice up and warm up any neighbourhood.It doesn’t have to cost a lot to knit a tree warmer if you use vintage wool from the thrift store or even an old unpicked jumper.Is this tree up for lease? I’ll take it.Anybody can take a crack at yarn bombing including girls & boys, kids & grownups alike.It’s fun to knit craft & sew & it’s always nice to snap a colourful photograph when it’s done.
