Am I on the right track? Or do I need to go back to the drawing board?

Excited to embark on this new journey of discovery in knitting and stashbusting. This is a mix of mostly cotton; silk, cashmere, linen blends. The paler peachy shades are a thinnish DK, so I'll double them with the Simply Recycled beige yarn for my A colour. The variegated cotton/silk/viscose is colour B. The darks are C, with a bit of astrakhan for texture. The mauve cotton aran will be extra A as needed and the D framing as I've got a lot of it, frogged from another fairisle project that has been a WIP for over ten years! @Zanete Hussain what do you think of this yarn pile? Will using mostly cottons be ok? I'm looking at this as an autumn/spring jumper as I already have Icelandic and fairisle winter jumpers.

these are my choices, I’m still not sure if the black, off-white or tan colour to add to the pink, steel blue and griege. I’m leaning toward the first photo with black.

I’ve been deep Diving into my stash and this is what I found. I think I’m well prepared now. I plan to held the green Isager yarn with itsself doubledstranded and then paired it with the green Zauberball.

Hi, I’ve got some merino75%\nylon25% left overs in fingering I could hold double to hit gauge. I’ve got some different colours I could do with your help to chose please. I’m pretty sure the slightly off-white will be colour A but I’m not sure about the rest of the colour palette. There is a purple-leaning brown that knitted up lovely that I think could pair with a dusty blue, a more vibrant light purple or a dusty rose colour and then I’ve also got a lovely light green I could use as a blending colour with either the forest green or a beautiful marled green/blue. I’ve taken black and white photos for contrast so think I’m ok there. Which are your favourites please? I’m not great with colours generally and would appreciate some more pairs of eyes and opinions but I’m leaning more to the last picture (marled green and light green)
