Talking about dyeing with plants... Here is the easiest way to get a nice plant print on fabric. Toddler shirts with unexplainable stains made me try to put more stains on those shirts to prolong their life just a bit. I'm trying to use everything until it lasts and reuse, recycle and upcycle to last a little longer, waste less, buy less. I hate to throw out those perfectly usable shirts that just look terribly dirty because of plant, fruit and berry stains that happens in enormous amounts for kids who live outdoors whole summer long. Well, pretty plant stains put on shirts with the hammer stay pretty for about 3-4 times in the washing machine.
I was dreaming to hammer plants on a table cloth last summer, but I didn't get there. This is an easy way to get the juices of plants on textiles you aren't planning to wash too often. Doll fabrics, a tie, maybe... altar cloths?
It's also a productive way to release anger, frustration and agression. I hope you will give it a try.
