I printed my nasturtium designs using paper stencils and a handmade screen-filler screen...
I printed the first layer using paper stencils under an embroidery hoop with screen mesh. I used discharge paste to print these designs - it takes the colour out of fabric, to leave a negative-looking shape.
When you print with discharge paste you can't see the print, except as a wet mark where the paste printed. Then you have to wait for it to dry, then steam it for about 20 minutes (e.g. in a colander above boiling water in a big pan - wrap your printed fabric in tea towels or some other fabric before putting it in your homemade steamer). After steaming you can wash the print and that's when the discharge print appears, taking the colour out of the fabric.
After the discharge prints had dried, I printed on top of them with normal printing paste (orange screenprinting ink), with the screen I made previously using drawing fluid and screen filler.
I'm planning to embroider over these pictures and make more layers using stitch.
