(No baby yet, booo!)
I saw some tutorials on pintest on how to turn Tshirt into yarn, and I thought its the greatest idea ever! My husband has a bunch of old Tshirt that he just used to clean stuff around the garage and toss. So I took some of the black ones, thinking it would be great for a chunky sweater. I tried looking up on the internet to see if anyone else had made a sweater from Tshirt yarn but didnt find much, so I decided to just start knitting it and see how it goes.
The Tshirt was cut into 1/2 (some times less) inch stripe and turned into yard. I used a size 15 needle and it knits up very nicely. However, after about 1.5 Tshirt worth of yarn, I realized that the end product is going to be super duper stiff, and heavy, and thick. Its not going to be comfortable as a sweater at all!
So I am here to report — unless you have the patience and scissor skills to make thinner yarn, dont use T-shirt yard for sweaters. They are super great for crafts though! I think they would make great rugs, placemat, dishtowel, and coaster!
