My fabric is a cotton poly blend from JoAnns. Feels really nice against the skin, sews up very well, but snags somewhat easily, unfortunately. I, again, used the tutorial on collars with stands from GigiSews found on this tutorial website, http://sewingtutorials.blogspot.com/2008/05/topstees.html, This site has some awesome tutorials. First you attach the inner stand to the shirt, then attach finished collar to the inner stand. Then the outer stand to the inner stand, just sewing around the ends and collar edge. Then you turn the whole thing right side out and finish the outer stand lower edge. You end up with such a nice finish, both inside and outside.
Check out the site, she explains it so much better and her pictures help where words can not.
Now, on to the sleeves, which are inserted flat. These sleeves go in without a pucker in site. Perfect. I added a 1 1/2" to the depth of the cuff, to allow a bit deeper of a roll up.
I highly recommend this pattern for anyone who loves a nice button up shirt.
Stay Happy, Keep Sewing!
