Like most crafters, I have stacks of products and purchases that have sadly been under-utilised. Something that definitely falls into this category is my alcohol inks. The biggest use I had made of these little bottles of fabulous colour is to blend onto left over photo paper and use on my cards.
I hate waste, and often find that you only use half a sheet of A4 photo paper for a project. I have gotten into the habit lately of using the rest of the sheet and making backgrounds with the alcohol inks. My preference is a combination of 3 inks so that the colours blend better together. Some gold ink was also "smooshed" in for some shiny contrast.
