You have many options for supplies depending on your purpose.
Things to consider are:
silk dyes or silk paints
setting silk by iron, steam, chemical
resist such as gutta, water based resist, solvent based and how to remove or leave in
My magic pens just don’t work. The ink disappears too quickly. I use a bit of vine charcoal or charcoal pencil to transfer my images to silk. Used lightly, they wash right out of the silk. Its great because I can spend a day transferring my work for the week, then just move on to gutta and painting whenever I like.
