I thought this was a site with a lot of soul.  Jewish Oregami.  Make a sevivon, a purim basket, and star of david from the instructions on the site.  The author also provides names of books by this name as well. http://www.origami-resource-center.com/jewish.html   

I ran across this catalog recently, and it has some very inexpensive crafts for toddlers, young kids to do covering all the holidays, and Israeli crafts too for Yom Haatzmaot. I haven’t purchased anything here, but could see these items being useful for party favors, activities for chugim (activities) , etc. http://www.jewishcrafts.com/Israel.html
