You can use just about anything for your marble magnet pictures -- draw your own (using Sharpies or other water proof pens), wingdings (I love these fonts!), envelopes, magazine pictures -- really, the list of ideas is endless.
If you've forgotten how to make marble magnets/tacks, here are a few tutorials:
Not Martha (great site, check it out!)
Or Roxy Craft.
Or why not try something different? Fabric covered thumbtacks are adorable and easy to make! Use up those bits of fabric you've been holding onto for ages by making these great tacks!
What's going on tomorrow? How much more organizing can we do? Oh we can do more, don't worry!
