Spiders may give some people the creeps, but I still think that their webs can be hauntingly beautiful. These paint resist spider web windows are fun and easy to make and would be great for a collaborative project or for a classroom. These are spooky enough for Halloween and pretty year round.
I love the reaction that occurs when you combine salt and watercolors. Salt paintings are a fun process that your kids will love.
Try sprinkling salt on a freshly painted watercolor picture and see what happens. It is lovely. Another cool process is painting on the salt with watercolors. This is a messy process, but a fun one that will certainly delight your kids. A word of warning, this technique is more about the process and the fun than the final product. There are changes that occur to the paintings upon drying. We have included some notes and suggestions about the salt paintings at the bottom of the post.
