There are 2 KAL's per month and they send out an email each day for a certain number of days. The email only has a set number of rows for you to knit and you have no idea what the pattern is going to be until you are done, or in my case almost done.
I wish now I'd used a solid colour instead of the multicoloured blue, but oh well, you can sort of see the pattern here :)
In case anyones interested the yahoo site is called Mainly Dishcloths and you can find all the past patterns here.
