Craft projects can be expensive. Every new medium requires some output of cash, so it helps to save money where possible. Lately, I'm really into using alcohol inks. The applicator for that uses little felt pads.
A package of 50 refills is $5. That's pretty crazy for tiny rectangles of felt. Instead of spending so much, I bought a 20-cent sheet of craft felt. I measured the felt pieces my applicator came with, then cut rectangles of the same size from my sheet of felt with a rotary cutter.
For a mere 20 cents, I got 38 felt rectangles to use with my applicator. Major savings! Every little bit helps. Admittedly, I hate measuring things, and it took a little time, but I think it was 100% worth it. And the savings allows me to buy a new bottle of ink. Priorities, you know.
