I feel like I'm cheating a bit today as this sleeve takes no extra drafting, but it's a fun treatment especially if you would like to use 2 contrasting fabrics.
Below, you can get a hint of the slashes on the sleeves. I began with a typical funnel neck top with set in sleeves.
I'm calling this sleeve treatment
The Skeleton Sleeve
as the tied slashes look like a vertebrae to me!!
To do the sleeve, you will want your first slash to start about 3" from the sleeve cap.
Find the center of your sleeve. Measure down 3" from the top of the cap. The slashes are 2" wide and are spaced 1" apart.
That's it, a very easy little treatment that looks interesting and nicely shows off the contrasting fabric underneath.
I really like this top and I wear it quite a bit. Since there are 2 fabrics, it's warmer than my other tops, a real plus for me.
This treatment can be done on other areas of your garment, but as I said above, just be sure that the fabric doesn't run when pulled.
