I have offcuts from 5 self-adhesive tape measures if they're useful to anyone. This is the original product: https://www.amazon.co.uk/gp/product/B0BHZDNL2Z/
I've used 30-40cm from (roughly) the middle of each so there are 10 lengths in total, 5 going left-to-right and 5 right-to-left. They all start after the 0 point. The adhesive hasn't been used and the tapes are metal so no risk of stretching during application. Collection from Pendeen.
