I made this rat for my daughter's cat, Burton. That was before I had my Bibi! I worked Burton's up in a kind of gray boucle yarn, and it was STILL easy to make! Junes patterns are the best! And I LOVE how she includes pictures and helpful hints with all of her patterns! I have made Bibi two smaller fingering yarn weight "rats" that look like smaller mice! She loves her "Mousie"!
I took a pic of the rat outside before I sent him on. My what a reaction I got from my co-workers!
Here is a link showing their reaction!
