The first was this collared polo shirt, #20 from the 4/2012 issue.
The striped fabric is a nice pique knit. It has a good weight but a good amount of stretch, too. I'm happy with how the stripes match across the body and sleeves.
The second is a long-sleeved T-shirt with some sleeve details, Ottobre 1/2010 #24. The fabric is leftover from this dress project.
I opted for a snap closure rather than Velcro as suggested. I find Velcro to be a laundry menace. The girls' tights always seem to get the worst of it...
