Hello there!
Welcome dear traveler to the world of possibly painful fingers (depending on your strength)
Firstly, i wouldnt buy from that etsy shop. Mostly as it would seem they are buying supplies from The Ring Lord and re-selling them over here. How do i know this? Because they are even using the images from The Ring Lords pages on clear plastic scales.
For a project this size, you want to be buying in bulk.
Now im going to state the obvious, the amount of rings and scales you need will depend on your size.
Ive had a few people ask me about making them a shirt/shoulder piece ect, so i have a few workings out ready for you.
TL;DR:
Small scales, 1000 per square foot.
Larger scales, 300 per square foot.
Now, if your working on average male larper size (i.e XL-XXL) your looking about about
15500 small scales, or
4700 large scales
for a simple shirt.
There are calculators online you can use exact measurements in to get a much finer idea of the amount of scales youll need.
And dont forget each scale needs 2 rings to attach them together! 31000 or 9400 rings to open and close!
In short, your looking at anything from £200-£500 in supplies. Its going to take a long time, and if your using steel scales with steel rings (i wouldn’t risk using alli, the weight needs solid support behind it!) its going to hurt your hands while you get used to it.
Personally? i absolutely love working with chain and scale. I fritter hours of my life on knitting and weaving. Nothing gives me the satisfaction of seeing a project come to life. Go round the league camp and listen if anyone’s crotches are jingling.
Thats my doing, scale mail codpieces, love em to bits. There’s a civil servant and the senator of Tassato wearing massive byzantine chains that took me nearly a week a piece to finish. But DAMN do they look good.
Working in the field, be aware you are likely to loose some rings and scales here and there. they are like the opposite of sand, they get everywhere other than where you want them.
I tend to have large glass jars or pots with a sizable amount of rings or scales in them and a bowl or suitable dish like thing to pour amounts of each to work with into. Minimizes loss and makes it easy to pack up if you need to be elsewhere, such as stabbing an orc or wooing an eternal.
Edit: What i wanted to say before accidentally posting this was, if you want some advice or to see what youll be working with, give me a poke on here and i can bring some of my various supplies with me for you to play with!
