So, I came up with the idea of making him a mini quilt that he could take to school to sit on, a 'sitting mat' as he calls it. I actually made two and we have been rotating them every 4 or 5 days allowing me time to wash and dry them to keep them friendly on his skin. Cotton strips, using the quilt-as-you-go method, with soft flannel backing, one in dinosaur print and the other in police print so he can tell which one is to bring home to wash and which one is fresh.
These were my 1st quilt-as-you-go projects, and I am quite chuffed with how they turned out, so fast and effective! Happy days!
