Kona solids PFD from Hancock's of Paducah is what I get. They have 45" and 60" wide in the Kona 60 square (60x60 threads), plus Moda 60 square (the same as Moda Bella solids), and also Kaufmans Pimatex (a 211 thread that compliments most commercial hand dyes). Mercerized fabric is best; deeper color. Unmercerized fabric dyes up much paler even with the exact same dye mix.
