This pattern is for a plain round neck adults t-shirt. I use this design and these measurements as the starting point for all my menswear patterns. I have created this simple design to encourage more people to try crochet menswear.
There are five sizes of shirt and three sizes of sleeve.
The pattern recommends DK cotton (up to 650g for XXL).
Pictures show striped versions of the tshirt and details are given in the pattern for these, but the overall instructions are for a plain shirt.
