Found this in Akureyri museum in Island
A sewn monks shoe made in wollen twill. Dated to first half of 15th century. Replica. The seam goes from the toe and under the foot and up the back of the heel.
There was also a sewn mitten with two thumbs (not needle binded) dated around 1400, see close-up of the fabric (couldn't take a picture of the mitten, the glass reflected too much, but it was very big)
