Cuffs of a pant/hoodie

Question

How are the ends of this pant/hoodie made? Can it be sewn at home? They don't have any elastic in them (from what I noticed in my hoodies)

I'm very new to sewing, sorry if my question might seem a bit stupid or too obvious.

Answer 1

There is special material at the fabric store to make these.  Tell them what you are making and what you are looking for and someone will be able to point you in the right direction!!
