Thanks for your help but I'm still a little confused. My pattern says nothing about psso. If you don't mind here is what the whole pattern says:
[yo,k3,(yo,ssk)three times,yo 3-to-1 decrease, yo, (k2tog,yo)three times,k3,yo] I hope you don't mind. It's probably right there and easy to understand but I'm just not getting it. Thanks again for your help.
