All my knitwear should be hand washed cold with a gentle detergent, and laid flat or hung to dry (be wary the knits may be heavy when wet, and hanging dry may cause some stretch). Do not use heat.
While hand washing will always be the most gentle method- Cyanotyped pieces can be either hand washed or machine washed cold (excluding knits), using a phosphate free detergent to avoid damaging the design. Machine dry with low heat. I recommend washing alone for the first few washes to avoid any potential color bleed onto other pieces. Cyanotype designs should hold up well when properly cared for! Please avoid over-washing and heat.
