I happened to walk into Staples last week and discovered Martha Stewart has worked with Avery and designed a line of products for home office.
The one product that impressed me the most was Chalkboard Labels! It is much neater and easier than chalkboard paint.
Sorry for the small images. Clicking on them will link you to the product pages.

Chalkboard finish seems to be ‘IN’ right now. Besides the labels, there are wall decals and contact paper with the chalkboard finish.
Good thinking! Leave it to Martha to come up with something so practical and helpful.
I love this idea! These are so great!
I´ve seen those before! Love them!!!
