I was captured by a Patons SWS colorway one day and knit a little bag using two skeins. It was nice, but not spectacular and I never did get around to felting it.
One day on Ravelry, I spied 3 skeins of a different colorway offered for sale or trade and soon it was mine too.
In August, my LYS had a weekend retreat and the technique that I wanted to learn was Entrelac.
I unraveled the first bag and used some of that yarn to knit the bottom of this bag, I then used 2 skeins of the new yarn to knit the first 4 rows of entrelac, the next two rows of entrelac was from the first yarn again and then the bag was finished off with the remaining skein of the new colorway. An I cord bind off and I cord tie and then into the washer.
I was a little concerned exactly how to do the felting in my front loader. I can't adjust the spin or rinse cycles and decided to check on the bag after just 3 minutes in the washer. Good thing as it was already as felted as I wanted it to be. I have a box in it right now and it's drying out on the back patio. I'll post pics as soon as it's dry and assembled.
These pictures don't really do justice to the vibrancy of the colors in this.
