I was missing about 19 colours for Errol, and that’s far too spicy an all-at-once purchase at UK prices.
So instead every time I’m down in town for something unrelated I just nip into the craft shop and pick up a few, thus hardly spending anything at all!
It totally saves money and I will not be taking criticism at this time.
Fun fact: this also works for yarn, fabric, thread, and even batting!
It’s the loophole They don’t want you to know!
