Traveling felt boards

Hello from Texas! The first leg of our trip is over. We have visited family in various parts of Texas and now my husband has returned to lone it in Chicago while the kids and I enjoy an extended visit down here in the DFW area. I do have access to a computer now and plan to update the blog when I can. Starting with one of our successful last-minute airplane activities.
The night before our trip I realized I hadn't put any thought into what travel activities I'd be packing for the kids. Oops. So, I pulled out my trusty Preschooler's Busy Book (book of choice for this season of our lives). I found a suggestion for a boxed felt board and adapted it to suit our circumstances. Instead of lining a box lid with felt and storing cut pieces within, I lined two sturdy cracker box sides with felt, adhered the cut pieces to the board and stuck it in a gallon-sized ziploc. Perfect for plane travel! This was prepared late the night before we left, so I didn't put a lot of thought into it, but it turned out to be a satistfying activity for my 4-year old. I plan to make a couple more for the return trip with different themes or generic geometric shapes.
