We went with a color scheme that is mostly brown, lime green and sort of a dusky blue. I'm going to have one lime green fleece pad for the bottom, and one that will be the dusky blue (for every other week). The pads are made out of fleece sewed to a cut-up cotton rich mattress pad from Wal-Mart. The small rectangles scattered here & there are actually small landscaping bricks covered with fabric squares from quilter's fat quarters. I used a lot of the ideas we got from this forum to make a couple of sleep sacks & one cozy (will try another one later on). This is a babyproofed cage for our small (young?) piggies.
