As you expand a product range and do more variety in your work you will need more storage space for small items ( chocolate chips, baking soda, vanilla, different varieties of grains and seeds) I have a small laundry room off of my kitchen, I got rid of my washer and dryer and sacrificed them for bakery storage. I do my wash at the laundromat so I could steal some more space for some shelving. Hopefully, you don’t have to do that! Here is the shelving that I use for my miscellaneous storage. Once again, there are assorted sizes to fit in a space, the shelves can be adjusted to different heights, and the plastic cambro tubs come in plenty of sizes and are stackable and should be used to hold nuts, seeds, and grains. I also use these tubs to hold my sourdough starter in. There are endless options for clear bins to keep small ingredients in. I keep things I will use together in the same bin, so I can just grab the whole bin out when I’m making cookies for example.
