Thanks for sharing the tip, Sadie. I may need to check those out since some of my Micron pens are drying up.
The ultra-clean crayons can be hard to find. Our Walmart had them mixed in with the regular crayons.
Heidi, I agree. I'm always looking for cheaper alternatives to things. I really would like to try copics but there is no way (unless I win the lottery) that I could justify the price.
