We found a great scale model of the Tabernacle. It is a plastic model kit that is very detailed and takes some skill to assemble. It included a high priest, 3 priests, a jar of manna, Aaron’s budded staff, the ten commandments stone, 3 sheep, 8 stands, an ark of the covenant, 3 lambs, 2 cows, a bread table, the altar of incense, the lamp stand, 2 breads, the altar of burnt offering, and a tree. The Tabernacle is built using posts and several layers of fabric representing the actual coverings used.
We used some flexstone spray paint to paint the base so it looked like the ground. We bought others paints (gold, brown, silver, etc) so we could paint the other pieces as nothing comes painted. The project takes several hours to build so it probably makes sense to build the project over a weekend.
We pull it out every year or so (especially if it is being discussed at a meeting that week) and take the coverings off and look at how it is constructed and all of the various parts that make it up. The May 1, 2010 Watchtower on page 7 has a great picture showing the various parts of the Tabernacle and what each pictured. We read the scriptures sited and try to remember what each part is and what it pictured.
You can find it sold several places online including Amazon.com. The model we bought was made by Vision Video and is called The Tabernacle Making (Model) kit. It is a 1:90 scale model.
