I am after some tips/advice from people who have made their own wrap.

I have brought some stretch Jersey? (like t-shirt material), about 5m.

I am planning on just cutting it either in half or thirds down the length. Not sure how wide it is, but if I make it about 60cm then hem the edge will that work?
I was planning on folding it over twice, to get a smooth edge then zig zagging it. I have to have a closer look at the fabric and whether it will fray or not. Could I get away with not hemming it at all?

I have looked on mamatoto, and that was the basic idea I got

How easy is it to do a pocket and is it necessary for extra support etc?

I thought I would try making one first and see how much I use it and I can decide to either buy another one or just make more. I may be able to make another wrap with the extra material or depending how wide it is I may make some baby swaddle wraps/blankets. Is Jersey ok to use?

TIA
