This cloth is named "End of the Rainbow". Here's the link to the pattern: http://knittingonthenet.com/patterns/clothrainbow.htm
I chose another colorway (one of my favorites) by Bernat Handicrafter Cotton, "Tiara Ombre" one of my favorites.
The pattern is very easy to knit...rotating garter stitch panels of 5.
I'll be making more of this pattern later (in acrylic yarn) to add to my stash of 7x9" blocks for the afghans I'll soon be sewing together. Stay tuned!
Have a great day!
