This is what I used for this quilt. Worked really well.
Measures 76x87 - 14.5" blocks

Quilt in a day has a pattern for t shirt quilt. I used Pellon 911 as stabilizer for my tshirts. It worked very well and made cutting the t shirt blocks smooth and easy. My t shirt quilt is on it's way to the LAQ -it turned out great.

I just retired from being a 4-H agent. I have camped for 20 years and made a t-shirt quilt from my camp t-shirts. They hung it at my retirement reception. I love it. I ironed woven interfacing to the back of the t-shirt with the stretch going the opposite of the stretch of the shirt.
I have never posted a picture. I hope it works so you can see it.

Has anyone used those nylon jersey shirts, like the ones kids wear in hockey, in a T shirt quilt?
Also, how do you quilt them?

Thanks for the tute. I'm in the process of making one right now. I've stabilized the shirts, but am stalled by the next step. Thanks for sharing the info.

My husband was from Kearney, Mo. Still have relatives around there and in Liberty, Mo.

I have made about 15 tee shirt and memory quilts. There is a light weight knit fusible that I like best, but any light-weight fusible is fine. If you use something too heavy it makes the shirts way too rigid. Make sure you use the stabilizer on the tee shirt before you cut to the desired size. . . I have done things a variety of ways - with sashing - without - appliqued onto a strip of fabric - I just go where-ever my brain takes me - my last two I did not use batting but used blizzard fleece instead - with instructions to the recipient to wash in cool water only! works fine and takes a fraction of the time !! I also always wash a quilt before I gift it !!

I use lightweight Pellon fusing.
I love making T-shirt quilts. So personal and creative.
My first for a granddaughter to take to college for her dorm.

Same here. I'm on my second t-shirt quilt and this is the interfacing I'm using.

I've read through most of the replies and another thing I did was to also back any design on the back or sleeve and then fuse them to an empty spot on the main piece - the front - and then machine applique them. That way all the "bits" are included. My cousin had 30+ concert t's and I wanted to include all the pics - turned out great and she was happy. The quilt was somewhere between a queen and a king and I tied it.
