Speedweaving European 4-1 Instructions

European 4 in 1 is the most basic chainmaille weave. It was used commonly for armour purposes, and is still the most used armour weave. It also looks nice as a jewelery weave. NOTE: as shown, this sheet does not hang the *correct* way; if hung the right way (90 degree turn as shown here), it will conform to the body.
The white rings are the newly added rings, The orange rings are ring(s) through which the new ring passes. The green rings are rings already added to the chain.
Step 1: Close four rings.

Step 2: Pass a new ring through these 4 closed rings, then close the added ring.

Step 6: Continue adding fivelets to the chain.

Step 7: Build 2 of these chains like so:

Step 8: Join the 2 chains with a single ring like so:

Step 9: Continue adding rings like in the last step until the 2 chains are seamed together.
