Turns out I probably could have done it, and it would have been great exposure to a ton of stitches. I think an Advanced Beginner could easily tackle it.
Instead of changing colors every round ('cause, I'm lazy like that), and in an attempt to use up all that variegated yarn I just can't stop buying, I decided to pull from my stash. (Good news - the stash is down 9 very large balls and I can see a corner of my desk!)
I think this one is stunning and I plan to use it as a table cloth in my kitchen. Best of all? The pattern is free on Ravelry.
Here are some more pics to enjoy!
