If you are ever in the area of Michaels craft store, stop in and pick up their craft calendar of events. They have wonderful children classes that are on most every Saturdays, especially in the summer, it will keep your kids from the "boredom" they are always singing about. The craft instructors work with your kids and it is an accomplishment for them. Also, when finished with the class, they will have a new talent and you can buy extra supplies and have them make more of what they made, and use them for gifts, etc. It is a wonderful idea from a great store!
PROS: great with kids, reasonable
CONS: need more classes!
