I always have some sewing kit with me.
If I haven't got my leather working kit with me then it's this little set contained in a Saami sewing pouch.
Most of the needles are contained in a replica of a bobbin and needle case found on the Mary Rose.
The larger needles sit on either side of the wadmal flap of the pouch.
I have a couple of other bobbins, one for more linen thread and the other for two different weights of artificial sinew.
A retracting Scalpel and a bog oak and antler handled awl deal with cutting and piercing.
There should be some bees wax in there somewhere but I need to put a new lump in.
If I'm going light I just carry the Mary Rose bobbin.
