I guess this easy peasy type of crafting is what I went for years ago, when I first started card making. It gives you a good grounding. However, I would only buy this type of kit now if I wanted to make some really quick cards for charity.
I am a bit sick of seeing Kanban though. Having said that, a lot of crafters must be buying it, or QVC wouldn't have dedicated Kanban, and Dawn Bibby design, (manufactured by Kanban), shows.
Nowadays, I prefer something more challenging, and don't make as many cards but spend a lot of time on other paper crafts.
We do have to thank Dawn for bringing the craft shows to QVC in the first place. Up until then I had to make my cards from what I could pick up in charity shops and haberdashers, or just do computer generated ones with naff clip art.
