Hand-dyed yarns can vary quite a bit in shade, even within the same colorway. If you knit through one skein completely, then another, you’ll see a distinctive line in your project where the two skeins meet. This isn’t a problem if you’re making a one skein project, but what if you want to make a sweater, a shawl or something else using multiple skeins of hand dyed yarn? Try alternating your skeins! If knitting or crocheting flat, work two rows from one skein, then work two rows from another and so on. If working in the round, switch skeins at the start of each round. This will blend the color changes together to transition more smoothly and will give you a much cleaner look.
This same technique can be used when using commercially dyed yarns from different dye lots.
