I love this shirt - I am trying to sew it for my daughter...but I am stuck on the sleeve construction and although many of you mentioned also having trouble, no one explained how they did it. Would anyone have a minute to do so?

I don't understand why there are three sleeve ruffles in the pattern when the finished shirt has only two ruffles?

Before I can even CUT my fabric (i wanted to different fabrics for the ruffles) I need to know how they go together. Do the inner and outer frills get sewn together? but why? that would just cause a seam down the middle? That is all I can figure out though. I hate it when Ottobre makes what appears to be a simple shirt sound so confusing!!

Any help would be VERY much appreciated!!
Thank You!
