Okay so I think I am finished with proof-of-concept sample of entrelac in double stockinette.
wow it seems to be actually easier than normal entrelac (no that I would know bc it's my first time doing entrelac OR double stockinette)
the principle from double-knit to do it on smaller needles than normally still applies
increasing needs to be done on both sides in every row, like they were separate even triangles; I think it looks best with Knit Right Loop Increase and Knit Left Loop Increase; KRL when the edge is to the left of the increase and KLL when the edge is to the right
there's no edge stitch necessary at all, i just go with double stockinette as normal and it translates perfectly to two layers
squares are almost perfectly square with very minimal adjustment because I don't need to do the whole "twice as many rows as columns" thing
I want zig-zagged start and finish from full squares instead of triangles, and think Twisted Chain Cast-On (formerly known as Chinese Waitress Cast-On) is neat, because I can cast it for every square separately, max 60 loops at the time, instead of casting 420 or 600 at once; however, this is rather dense and stiff cast-on when amount of columns is effectively halfed right after casting, so I might tinker with it a bit more
keeping sides separate is a bit tricky for modules' edges, but it gets easier quickly
the trick when joining the module to the living edge is that after casting from the selvedge, I have on my left needle 2 loops that are to be joined in this round, one to every layer, and I find it best to group them with their respective loops of the current module beforehand – uhh. This doesn't sound clear, does it. I think I might just do some photos when I get to that point again
all in all, it creates such a clean cute reversible effect, it really does feel like cheating. It might be easier than normal entrelac for me
i think it might be perfect blanket pattern for me? my platonic blanket texture and grammage is boiled wool, blanket needs be sturdy and warm and not hole-y at all, so I was always extremely apprehensive towards knitted blankets; but this, small air-holding pockets of relatively dense knit, this is perfect while also having a potential to be wildly decorative
I'm going to test whether I can incorporate invisible cast-on for double-knitting, and if I can, I'm off to my target yarn
my target yarn, my beloved storm-colored discontinued Alize Bamboo Fine Batik which started all of this because the whole "entrelac but smooth stockinette" concept because I refuse to use it on something that doesn’t maximize both its stormy gradients and it's touchy-feely smoothness, which mere 6 or 8 years after buying will be finally used up and appreciated by all!
