THAT MAKES CENT$ -Using plastic keychain store cards

HELPFUL HINTS:
Do you have a keychain loaded down with those little plastic store discount cards?  You can always use the outdated or unused cards as an art tool, they work great as: 

* A Scraper to remove paint.  
* To Remove Masking Fluid.
* A Template to make little rectangles of paint color swatches in your sketchbook.    

UR-TURN:  Share other ways you use these little plastic cards as an art tools.

Until Next Time.

Many Blessings,
