Actually professional laundries have long known that the use of fabric softener... conditions textiles. Giving fabrics a smoother feel. It also aids in ironing allowing fabric to lay better without curling around the edges and allowing the iron to glide easier over garments/linens. Softener or conditioner...regardless of what its called all does the same job.

Check on ETSY to find this. There are a lot of online drapery workrooms there. They show their fabrics. This looks to me like a synthetic ground with lovely decorative detailing and it will be very difficult to replicate unless you get it from the same source. When I have ordered samples from workrooms on ETSY, they always come from obscure sources in faraway lands with little to no labeling. I think this might be your case. So, I'd scour that site first. Good Luck! Alternatively, you could pick up one of those pinks in a solid perhaps, or a companion print/pattern which I would recommend engaging a professional to help you with the nuances of the task.

Tartan, this one is thanks to Instagram. :D I see so many design accounts — wallpaper, furniture, fabrics, furniture, rugs, etc — it’s amazing how often it’ll be something someone is asking about here. And I used to work in the field, so remember a lot of sources. :)
