I can do some craft type items, to supplement. I have a line of Infant Wear I can sell, and when income is needed, I make up a bunch and place them in local and area consignment shops. We have developed some crafty items that do sell well, so keep them in mind when more income is needed. We do yard care for our landlord, which they pay us for, and we turn around and give that money back as part of the rent. People are always needing a quilt top sewn, a baby item made, repairs done, or something that adds income.
Every little penny helps when it comes to adding to a small, fixed income.
Our biggest boost is the fact we do not buy on credit. When it comes to birthday's, anniversaries, holidays, or any gift giving time, we make them, and usually from things we have around the house, or at least that do not cost much to purchase. I package it into single use sizes. I just use a simple cheap sandwich bag, then place the individually wrapped bag into a freezer quality zip- lock. We do the same with vegetables.
