Here is my batch of red onion skins. The best source of onion skins are the grocery store. The clerk at the register might look at you funny. If you have a farmer's market, they are more than willing to give you their skins. This batch was also split into two batches.
Here are all four dyes that will sit in their containers will sit for about 5 days.
