I think thought they looked quite pretty. I'm not sure that the poor little cress seeds enjoyed their lifetime in the wool though. Not many grew.
I might not have put enough seeds in. Or it might have been because a certain small person kept knocking them off the window sill when jumping up to see the recycling trucks, but whatever the reason, we didn't have enough for egg and cress sandwiches! Maybe we'll try again, with more seeds and a safer location. I may revolutionise cresshead growing yet!
