Strap leather strips pre-punched for making breastplates. These will really save you a lot of time on your next craft project. This is a 24" strip that is punched every half inch, for a total of 48 rows. Priced each, but sold in multiples of six.
You will need four strips for a full size man's breastplate. The average sized man's breastplate takes 33 rows, but you will want to make it longer if it is for a person who is very heavy or very tall. If you don't need the excess, the scrap is perfect for a child's breastplate or mini-breastplate choker.
