A while back while reading The Tightwad Gazette I came across the idea of mixing leftover paints to create new colors with which to paint. We had a whole gallon of blue left from the living room accent wall and various shades of white left from the previous owners. We also had lots of leftover painting supplies from our other projects.
We purchased 1 quart of orange paint and some painter's tape all from our monthly budget, so our cost was very low.
We LOVE the results. It took us just under a week to finish. Stripes take a bit of time as you have to let one color dry before painting the next. And when you have a 2 year old, you can only paint when they are asleep lest you end up with multi-color finger prints on everything. But when said toddler doesn't like to sleep in the guest bed, and wants to sleep in their 'wittle bed' your painting time becomes even more shortened.
The final result. Nice crisp lines using the tips from Centsational Girl.
