I purchased a Mock Turtleneck at WalMart about a year ago for $1.00 in the clearance section in the back aisle of the store. I have been waiting for some free time to make it into a t-shirt. First, I removed the neck fabric. Then I used wide twill tape to stabilize the back of the neck. After that, I appliqued a piece of pique fabric to the front to make a base for embroidery. Then, I hemmed the sleeves.
