One of the tools that I've added to my belt this past year is Derwent Ink Tense pencils.
They aren't traditional colored pencils. The "led" is actually ink. You add the medium to your image and add water to spread the ink around. It's like magic. You get vibrant color that is water proof after it's dry. The only thing, is you have to make sure you get all the pigment wet and spread out, or it will reactivate with any wet medium.
I have been practicing and when I saw the Color My World stamp set from WPlus9 I knew it was just the right stamp set to try it out on.
This set has some very cute hand drawn art supply images that are a hoot to color. And the sentiments are so cool. I stamped the ones I wanted to use in Archival ink so I could use water without smearing the image.
I used masking paper to mask off the images and make a one layer card front. It's important to use water color paper when you're using ink tense pencils. Regular card stock will pill up and you'll be very sad.
I used a water brush to move the pigment around with. I find it easier than having a pot of water on my desk. I spill things. I do keep a paper towel handy to wipe off the extra water and color.
I used a fancy corner chomper from We R Memory Keepers to dress up the corners and added the panel to a card base.
