It seems like traditional weaving, but the 4 holed tablets give a “two levels” warp.
And depending the way you put threads in tablets they will go right or left (very useful for geometric patterns).
It takes a longer time to prepare your work.
For this pattern (which is 2.5 cm/1” wide) I have 24 tablets, so… 96 threads (plus warp of course).
I have made few bracelets, but there is two much threads to make a nice knot at the end.
The fourth one is a “double side” with inverted colors.
