Today I bleached two large pieces of unbleached 28 count and am happy with the result. A very neutral lighter tan, still brownish, not at all too light. The original fabric is the folded piece, decided to only lighten two at this time.

This has happened before and I never did find an answer. The water in this bucket was from the very light wash I gave the linen to get rid of that water repellent finish. It's like sizing on most fabrics and I always remove it before dye/bleach. Since this linen was unbleached, this brown water can't be from excess dye, so what is it? Stored in plastic yet the wash water is always dirty. Are we stitching on dirty linen? Does the unbleached retain a residue since it is not processed as those dyed and bleached? Is natural or raw the same as unbleached? Any thoughts?
Remember when I took apart my older samplers and realized how dirty the glass had become? Professionally framed with sealed backs, yet this film can really obscure the stitchery. What an enormous difference once that glass was cleaned. My earlier stitching was all unbleached so I can't say if the other linens emit the same off-gasses. Would this be reduced if washed first? Does the finish I find (almost water repellent) on the fabric contain something that adds to this? I'm just full of queries tonight. And I expect answers.
