First I'd like to say that I am so thrilled that more players are interested in making carpets from ingame items! :D I am also honoured that you used my floor as an example. I have made a list of the items I used at the bottom of this post.
I made this quick guide for making carpets for my instagram:

I wrote this in my instagram post:
"When making a carpet there are a few things to have in mind:
*try to fill out the entire sqm to minimise the gaps in the carpet
*use items that give a uniform, flat surface
*use colours that harmonise unless you are deliberately making a patterned design
*use colours that are a good contrast to the furniture and items you will display so that the carpet stays visually in the background instead of competing with your items. After all it's just a carpet xd"
When making carpets, I prefer to use cloaks and armors as the base layer because I don't like the strong black shadow on the folded tapestries. Spirit cloak, glacier kilt and zaoan robes are among my favourites. I also use a lot of foods in my carpets because the stacks of 10 often fill out the sqm quite nicely. Coloured eggs are also a nice base layer. Same goes with most of the replicas sold by the npc Cillia in Thais Museum on sundays. I generally use the weapons in the "valuable" category because I think the movement effect on the "ornate" weapons is too distracting. But that is a matter of taste :)
For the medium and top layers these are my favourites: glooth farina
, solid rage
, spiderweb clouds shreds
, spider silk
, flour 
As for the items in the disco floors, I used a huge variety and I am not sure I can remember all, but I will try. I did use void carpets as a base though. but it will work without if the original floor is dark enough. Except for the pink one where I can see a bit of the carpet underneath. All tiles have a spiderweb clouds shreds
as the top layer. As this was meant to be a disco floor I used a lot of items with animated effects and I tried to make the effect unique for each colour.

, zaoan robe
, shockwave amulet
