I don't think it's too early now we're in December. I haven't bought mine yet but will soon. Only got one so far, and that came early because the sender was going away for a while.
I'll hopefully finish designing and printing my cards in the next day or two. I might then post those that don't require a letter inside but it will probably take me a few more days to pen appropriate notes to go in the others.
Chris agree with Minty and Scorpio, but I guess you get lots of enjoyment from designing your own one offs. Their might be a market for them, or designing bespoke Christmas cards / events for people if you want to?
Iposted a big batch of cards off on Friday and another big batch off today. Ive still got plenty more still to write. Yes, cards are coming in thick and fast now, at least ive made a start!
