As shown below I stuck mainly with the blue on this card, adding a little bit of pattern to the bottom and then adding those beautiful skylark accessories - also in blue. The yellow was pulled as a complimentary color to add a pop.
With this card I added a sentiment on the inside and decided to leave the front simple. I really enjoyed how it turned out - even though that is not something that I typically do. Also remember to stick to the 3-5 colors per project because as you can tell that this card with 4 colors it is beginning to get a little busy.
