We do not have dye lots as all our yarns are hand dyed or hand painted in small batches using non-toxic dyes; as a result each skein may have subtle differences. We will also, on occasion, have de-stash yarns available; de-stash yarns are new, never used and no longer needed for projects. We part with our de-stash to make room for new projects. Colors may appear differently according to your monitor settings.
