This cloth is my latest in a series, an ongoing addiction, quite frankly! So many of my friends love to travel in their trailers, it seemed the perfect design choice. Slip stitch knitting, also known as mosaic knitting, is one of my all time favorite knitting techniques. It appears that you are knitting with two colors at the same time, but you are only using one! All the knitting is garter, so simple. If you reverse the colors using the Universal Yarn Cotton Supreme, you can get 4 cloths from two full skeins! One for you, 3 for friends!
