I founf a knifty knitter patern on the proco craft web site for a water wave shawl. i have started it and I am halfway done put the instructions are not clear on how to finish it . You have to decrease the stitches but I am having trouble figuring it out It also doesn't tell you how to end it. Anyone that has done this patern or has seen it and knows how to decrease it so that it has the scalop edge. i could really use your help. It is very frusting when you don't have the whole pattern. Thank you for your help
