Since tea stains the tablecloth. . . I'd say it's a pretty fair bet that it will do the same for your lace. Fibre content on labels usually has the higher percentage given first, if that's something that can be read. Tea is one of those things high in tannin - so is coffee. Making either stick to cotton permanently is iffy. The dye exercise may have to be repeated. Could the trim be velcroed on?
Also consider walnut skins (the green bit from around the nut) this is quite strong, so maybe build up the concentration - same goes for tea, especially black tea. Green tea has less tannin, so is also an option.
Polyester has to be coloured in its liquid state before turning it into fibre, so depending where it is in the lace, there may be a speckled effect. Trial dip in a cuppa highly recommended to avoid nasty surprises.
