IMO Kanban kits are good quality and okay for beginners. But it can take me up to 2 hours to make a card, and most of what goes on it I have also made myself. IMO that's what crafing is all about. Not just push out and stick on. Personally, that takes all the enjoyment and satisfaction out of crafting. IMO a Kanban card looks like one that has been shop bought. I have bought Kanban kits in the past. But these were for a charity, when I needed to make a lot of cards quickly, but they're not very cost effective for such events. I don't wish to offend anyone. This is just my opinion of course, as I am aware that a lot of people love Kanban.
And, yes, it was Dawn who introduced them to QVC.
