I like unusual shirts and recently took it upon myself and my wife's sewing machine to start making my own shirts.
I ran into this rayon challis in the fabric store and decided I should have a tropical shirt of it. Converting my pattern to accommodate what I've heard about rayon challis involved turning the side seams and arm seams into french seams (after adding to the seam allowance on the pattern).
Surprisingly, it fits perfectly. It's not perfect by any means, but it's the first shirt of this fabric type that I've ever owned.
Looks amazing! This makes me want to borrow my mother in law's sewing machine
In my opinion, if you are interested you should.
It's very satisfying to wear a shirt that you created and that no one else can even own because you made it. Just make sure you watch some tutorial videos and don't let fear of failure get the best of you
If you are worried about losing the fabrics value from messing up, consider picking up some super cheap cotton muslin to practice on. Near me it is as low as $5 a yard, So a practice shirt could be 10 to $15 worth of muslin
