(plain old cardstock)
And used this:
(metallic rub ons, paint dabbers and embossing folders)
To make these:
(First put some cardstock in an embossing folder and run it through a Vagabond, Big Shot, Cuttlebug, etc. to emboss the cardstock. Apply the metallic rub ons by rubbing your finger in the desired color and then rub that finger onto the embossed cardstock. I like to make little circular motions. Then I applied a little Ranger Paint Dabber along the edges. The purple bubble piece on the left was covered entirely with paint dabber and then I wiped off the high spots with a damp paper towel - no metallic rub on was used at all.)
Which have turned into these:
(with the addition of a little ribbon and a stamped image, sticker or even a postage stamp)
All of these cards were very easy to make and should only require a 44 cent postage stamp to mail!
I hope you have time for inky fingers today!
