Quick question about folded cards - do you crease and fold them yourselves or do you buy card stock in ready creased? If it is the latter do you have any problems getting the stock to go through your printer?
For myself I prefer to use card stock and crease/fold myself with a bone folder since I can use it for multiple purposes/sizes. I have never had a feed issue with prefolded cards, make sure the paper isn't too thick for your printer to load though!
