Gorgeous cool toned mid range dusty blue linen...feels like a cotton/linen blend, the cotton adds softness and drape. Shirting weight, not too light, not too heavy, perfect for spring/summer shirts, blouses, tops, but would also work for a soft pant for warm weather.
Some pattern suggestions: Rachel Comey great little top
Marcy’s asymmetrical peplum shirt
Katherine’s BIG shirt:
Lynn Mizono big shirt
Pre treat by hand laundering or machine wash gentle and air dry. You can toss linen in the dryer if you want all over wrinkles, but always pre test a sample, some fabrics respond well, others not so well. Test Test Test. After laundering hand wash or machine launder gentle and air dry. I like to take my linens out of the laundry while still very wet, hang on a hanger and pull and smooth the seams and hems, allowing the weight of the water to do the work, then touch up with an iron or not.
