I find that using a 6x6 size is easier for me, since I am so used to working in a 12x12 format. I find cards hard for me for the unusual shape, but working in a 6x6 is a fit for me!!
Clear it Out has a wonderful challenge out there right now to color. So the challenge for the next two weeks is to show your projects using any coloring mediums. I am not a huge stamper, but I have so many, so I broke out this really cute flower stamp I have and tried my hand at coloring it in. I have never done this before, and it was so easy. I do not have any special markers (copic or the like), so I used my Bic marks a lot markers and they worked fine.
Frosted Designs also has a challenge going on right now to used trim or ribbon. I used a pink ribbon to run across the bottom of the card, and then I added a little bow at the corner of the "thank you" tag. I am horrible at bows, but I think my little bow here turned out pretty good!!
