It can be used in many different size yarns and hooks to get different size "motifs". With a worsted weight and 'I' Hook, I made something big enough to be a trivet or a dishcloth.
I have edited this pattern myself, so if there are any errors, please send me a note and I will correct the pattern.
In the attached photos, I have used two different color yarns, but this is not included in the pattern, as I did this more for a tutorial effect. I think it makes it easier to see the different rounds.
