I have some experience sewing with both wool and placing elastic bands. I've made my own historical reenactment clothing from the Viking age (lots of wool and linen used). I already have some 100% wool felt on hand, so cost for supplies will be less. I also have a serger, so I can finish the edges of the wool in any color you like.
I do currently work a full time job (mon-fri), so I'm placing my bid with a slightly longer delivery date to give myself a reasonable amount of time to finish them in. However, due to the fact I am estimating a longer delivery time, I am also offering a lower cost to hopefully offset the fact it will take me a little longer than others to finish the project for you.
