Those old sweaters that you no longer use can be repurposed into new home items like DIY mittens. That's the beauty of DIY, you get new items for zero cost. You just have to look around the house to find items that you don't use anymore, and use these
RIT DYE:If you use 1/4 cup salt and 1/4 cup white vinegar the first wash, it will set the colors so they won’t fade or bleed during follow up washes. You can do this with red shirts, and new jeans as well. I usually dye several things (usually onsies) the same color and then wash each color on an extra small load by themselves for the first wash -- Good to know for my dyed shirts!
