I’ll use the Manchelopis single stranded, with the Kidsilk Haze Colour.

Tips to separate the strands on Manchelopis:
Get someone to help you, then you can wind a ball each. Instead of pulling out the doubled up yarn from around the plate with it on the floor, hold it at the side and unwind it by turning the plate, and not the yarn. That keeps it from twisting.
If it’s on the floor and you unwind it, it twists… imagine a tape measure wound into a circle, and pulling it up from around the edge, that’s what happens.
Unwind some, gently pull the strands apart and off you go. If it looks like a tangle, just shake it…

I’ve also read that another option is to alternate, as you would when working with 2 skeins of hand dyed. Use one strand, then change to the other, and so on.
Yet another option is to knit with one strand, and roll the other into a ball as you go, but that makes for slower knitting!

Finished weight, 142g I used all 50g (420m) of the KSH colour, and ran out on the last row. I had some dark grey KSH, so joined that to finish the row and bind off.
I used 92g of Manchelopis, but as I’d split it to use single stranded, it totalled 422m.

I used the Icelandic Bind Off (my favourite for garter stitch):
