I will add pictures as the box comes along. We will be using beatlekill pine, tongue and groove. Some Texas stars for decorations, a drawer at the bottom. Thsi will be on wheels so that it is very easy to move around. The horses name will be engraved above the doors, and when it is closed the doors will cover the drawer for supplies at the bottom. I have spent a lot of time thinking about it and now my middle school students are designing in in a CAD program as well as adding some new twists!
Timber I did see the box from mydrafthorse. That one is more for show harness that comes apart. This one will be about the same size, better tires and will have double doors and a drawer at the bottom
Country women and Taffy Clayton - Thanks for your comments and I will be uploading pictures soon.
