During the paper-making process there are occasional things ~ artefacts ~ that get into the pulp. Typically in recycled paper this might be flecks of printer's ink that have not been removed ~ it is not easy. You might find an insect ~ as I recently did. Typically in some handmade papers there are flecks of bark or dried grass that have missed the various screening processes.
There are also deliberate additions to the pulpy mix. I am not discussing ~ dyes ~ chalks ~ resins ~ sizing agents ~ additional fibres (such as linen) ~ and all the many other ingredients that are sometimes used. I am thinking of things like petals ~ seed heads ~ chopped-up hairs.
Handmade papers ~ typically from Nepal ~ are readily available with petals from roses ~ cornflowers ~ marigolds ~ or mixtures of these.
Two Rivers papers from the water-wheel driven mill in Devon produce runs of petal infused artist's paper, using a mix of ~ cornflower ~ larkspur ~ marigold
Paper from Favini ~ in Italy ~ is made with a high percentage of novel materials that give it interesting properties ~ oranges ~ lemons ~ grapes ~ sweetcorn ~ nuts ~ lavender. It is not easy to obtain here in the UK ~ I will be glad to change that remark when I find out good source for small purchases.
