Make fantastic sun catchers with Klutz's Window Art activity book. It's as easy as squirting mustard on a hot dog. On the front of the book you'll find six bottles of color filled with a special squirt-on paint that will dry in 24 hours to make a tough film of color that you can peel off, carry around, and then stick down to smooth surfaces like windows and mirrors. Includes over 100 patterns and two alphabets, and six paint tubes. For ages 8 & up.
