Planet Dexter's book, "Pattern Block City," by the editors of Planet Dexter is a 48 page picture book plus a set of 32 pattern blocks. Each picture holds a different scene with a different picture to complete with pattern blocks. If I remember correctly, I ordered it from a Scholastic flyer.
Stomp Rockets - I found a mega-size package of them at a warehouse club
Rocket Balloons - A nearby drug store chain carries them
Write Shop's Story Builders. I was slightly familiar with these little gems before I reviewed them. Here's an example.

Family Fun magazine. I don't want to subscribe because I stopped all of my magazines because they were piling up. I have attachment issues with magazines. (I have managed to limit new subscriptions to just TWO, and they're homeschooling magazines.) Back to Family Fun magazine: I have a three-ring binder filled with ripped out magazine pages and instructions printed from the web site, stuffed into plastic page protectors, which I pull out from time to time to give me new ideas. The magazine and the web site are non-stop idea generators for arts & crafts, science experiments, and games. When friends and acquaintences asked me how they could help in our autism intervention, I asked for their old Family Fun magazines. The dentist sometimes saves them for me. And I look through them at the library. Many of the magazine ideas are also available on the web site. A subscription is inexpensive, too, if you don't get too attached to your magazines.
Taro Gomi coloring books. Google "Doodles" and "Scribbles". Yes, they're worth the price.
We have really enjoyed the artist quality drawing pencils I bought. Splurge on them -- they were worth the spurge.
Craft paint and little wooden cutouts to paint. The craft stores have a variety of little wooden cutouts that are fun to paint. Some are a quarter each. Watch your Sunday sale papers for the paints to go on sale.
Rubber stamping. Look for rubber stamps at yard sales.
Spinner. Okay, we have not played this because my daughter took the pieces and played with them and lost a bunch. We used to play this w/ friends BC (before children), and it is a fun spin on dominoes, and if I could find all the tiles, we'd play it! :)
