Rusty,
You might want to consider starting out with a soft-sided travel pack until you have the room and your little boy isn’t so much of a worry. Orvis, JW Outfitters, LL Bean–several companies make systems with zip lock sleeves, pockets, bindings, tubes for organizing threads, hook boxes, etc. that are large enough to accommodate most everything you would need for several years of tying dozens and dozens of different patterns. When not in use it can be stored in a drawer or closet. Eventually you will want something portable, this way you start out with portability and something that is practical for the here and now.
