I bought a t shirt online, that is way too long, making it look like a nightie( not a good look!) I need to cut about 4” off and hem it. I’m mainly a quilter and craft sewer and although I have made clothes way back in the past and scrubs during Covid, I’ve not really used stretchy fabric.
 Does anyone have a Janome machine, who can advise which stitches are best? I’ve googled, but can’t find anything too clear. I’ve got a TXL607. I’m guessing that I’ll need to finish the edge and then turn it up and hem.

Looks tidy compared to mine @Bodgeitandscarper. I have so much dumped in there now I have to step over stuff to get to the chair- which is piled up 

A bit thin in the SR's today. I've been up there getting nowhere fast.
Think I've done it now but will look tomorrow with fresh eyes 
 

I started doing the first wedge (dart?) on the waistband of a pair of chinos. I cut the wedge twice, as I didn't leave enough excess to fold back on the first one. I pinned it and tacked it to one side, then halfway through stitching proper, I realised I had threaded the needle with regular sewing thread, instead of the jeans thread I'd bought for the job.

 

So I ended up (almost) stitching again down that same line with the same thread. I left the general purpose thread in, and offset the jeans thread to it very slightly. After that, I pinned the wedge in place to do the other side, but my eyes got tired, and stomach started growling, so I broke off for a while. As I sat there eating a Cumberland sausage and fried egg butty, I decided food like this is worth having to let a waistband out a bit...

I might pick it back up again later, even if it's only to run a tack line through. I would like to try to get one side complete though, if my eyes are up to the task.

No. Sewing for me, today. Just back from a trip out with Eldest and not even had lunch, yet.
