Every skein is dyed with professional acid dyes and with a lot of love and care! I use a variety of techniques to get unique colorways. One of the beauties of hand-dyed yarn is that each skein will be slightly unique - some may have more speckles, some  a little more concentration of a color. While I do use specially crafted formulas to keep colorways as consistent as possible, no two skeins will be exactly the same. I recommend that you alternate skeins every couple of rows when using more than one skein of the same colorway. If you order multiple skeins, I will do my best to match them as best I can. I am the sole owner and dyer at Speckled Finch Studios and only dye in small batches.
