More collaged tshirts - what to do with parts of tshirts

Like I said previously, a million times previously, I am working on actual clothing, but work is has been nuts and the UFO and mending pile is easier to deal with than a new thing from scratch. Or a new pattern to alter. And there's more choir hems. 

I stumbled across this photo in my 'ideas' folder while looking for medical records. Isn't that how it always works?

which is from this

I taped together and am presently staring at this VersitiliTee from way back and.... it's not going to do what I want it to do. It has that solid piece front, with any shaping seams on the back, and while this does appeal to me in that ATATAC origami zerowaste manner, I need seams, my butt is big so I need the hem to be wider, and I just don't want to set in a knit sleeve. Not unless I have to.

I don't like a raglan sleeve - my shoulders have disappeared and I don't like being reminded of that. I want a seam at the top of where they used to be. So I enjoyed widening the bicep on this pattern, but alas not to be. Not a wadder but not for me; and you know about learning from failure by reading this blog.

And I have all these tshirts with images on them I love, and I am not going to make a tshirt quilt. Nope.

This style is just offset enough, the cut just abrupt enough, that i think it might work for collaging a tshirt. 

I had a long sleeve pullover knit similar to the brown shape, and I wore it to death in the late 80s.

So this is where my mind is going with this project these days
