Money's tight. We get it. It doesn't matter if you're an uber-successful designer or just starting out with half a client and a slice of toast to your name, it's important to keep an eye on your cash flow. Pinching pennies where you can certainly helps out. You don't have to be cheap to do this either, just be frugal; spend money where you feel it's important, and cut everywhere else. In accordance with that system, illustrator Caisa Nilaseca created these pics for Design Taxi, putting into imagery some pretty solid ideas for keeping those greenbacks (or whatever color the cash is in your country) in your pocket. And if that wasn't enough, feel free to check out some additional ideas for making money as a designer.
