Silk soon absorbs the dye colour in the strong Tansy dye bath. As this silk can be matted slightly by over heating, and simmering, I only introduce it to a hand hot dye bath. I left it soaking overnight to achieve best strength of colour before rinsing out several times in warm water, until water runs clear.
Wet rinsed silk - drying. Do not squeeze out too hard, or twist creases may occur which don't completely iron out. In summer silk dries fairly quickly and can be ironed smooth while still slightly damp before any creases set in.
A few dark 'spots' are splashes from another dye bath with iron I was doing simultaneously. Only do ONE dye bath at a time.
This lime yellow is very vivid (see comparisons with other gold colours), so I will overpaint with silk dyes or bundle leaf prints. However, it could be useful to over-dye with madder to give a good orange, or with woad for a turquoise blue. The future life of this piece will be posted here....

Post script.../ This lime yellow was over-dyed in November, used for another test with sycamore leaves bundle-dyeing; I didn't think I would use a bright lime yellow, but must replace as a sample.
