Exploring quadruple weave

With doubleweave one weaves two cloths one above the other, normally on four shafts.These cloths can be joined at the selvedges as you weave to create either a tube or a double folded cloth (joined at one selvedge only). With eight shafts one can weave four cloths and this opens up many possibilities.

Whereas a cloth in 8/2 cotton might have 25 warp threads per inch width (10 threads per cm), weaving four cloths one on top of the other means there are now 100 threads per inch (40 threads per cm) - which makes dressing the loom a little more cramped to say the least!

these first explorations are just to try the different techniques and structures so I've been easy on myself colour coding the warps for each of the four cloths and starting with a 5.5" (12.5cm) wide warp a couple of meters long.

The first section is weaving a tube within a tube - effectively a bag with a lining. Next I brought the lining to the outside and the outside to the inside. Still a single bag but with a "waffled" wall. 

With two layers to the walls of the bag, I tried a bit of leno lace. Hand manipulation of the outer cloth warp threads to create an open structure which allows you to see the cloth below peaking through.

Next I wove four separate layers (4 rather than 2 shuttles required) to form a pair of open ended tubes around the top of the bag to accept a pair of drawstrings.

Finally, a pair of tubes side by side that when turned inside out into the bag already woven will create double lining divided into two sections.
