When creating cards for others, we tend to want to put all of our love into creating the card and that, in turn, leads to us, as crafters, OVER-accessorizing our creation.
Some artists have this mastered and the effect can be AMAZING and other times it can just look cluttered.
I challenge you to "simplify" your next card design.
Use only a few supplies; a stamp, a few sheets of patterned paper, maybe a sentiment but make a point to reduce the amount of supply you use on one card. You will be amazed at how many cards you can create in a very short period of time.
