I have a variety of supplies I have collected over the years. I really enjoy using the ones developed for train enthusiasts to use. For what I have collected I have separated by color. (My favorite way to sort.)
I most everything in a three drawer cart.
A drawer for greens
A drawer for flower colors
A drawer for browns, black and whites - which includes various sands that might be used for dirt and ground
For all of these I use a lot of zip bags. I have found these to be the best option. To avoid dealing with the materials getting in the zip part, I use a metal bead scoop to dip out of the bags. I rarely use it for beads as I have mine sorted so am not typically dealing with larger quantities of beads. But for landscaping, I like dipping versus pouring. I do use a paper plate or something under my project to capture the excess and pour back into the bags.
Another bunch of landscaping I have is dried materials. These have a tendency to be larger packages, so keep them in a large box in my closet.
I do take a smaller amount of the dried items and put in a small bag to keep in with the three drawers of landscaping supplies.
Come back tomorrow for another organizing idea during my 31 days of organizing.
Happy Miniature Organizing!
