Silk Paints (Jacquard Brand), water based resist (note to self: purchase heavier gutta next time) and six yards of12 mm raw silk (only available on line): slubby and heaviest available. The silk was ordered from Dharma Trading for about $6/yd. Wash the fabric and dry in dryer on medium heat. The product says there is an 11 percent shrinkage fabric on this silk. This is correct!
Process: silk fabric was cut larger than the chair seat and a large canvas frame was turned over and re-purposed for stretching the silk canvas. A heavy staple gun was used to attach the fabric to the back of the canvas frame...the staples are easily removed after the project is completed. Resist was applied and painting started. Note: Allow paints to dry thoroughly and then steam following the technique using newsprint for wrapping and steaming (three hours). I used this tutorial from Dharma. Newsprint was purchased from the local art supply store.
As a learning experience, I used two types of silk fabric paint. One product for painting on silk must be steam set for three hours to set the dyes. The advantage of this type dye is that it allows colors to flow into one another and results in greater control of the colors.
These are a couple of pictures using this steam set type silk dye and paint brushes with the too-thin resist that spread much too freely, creating large areas that were barriers (resists) to the liquid paints.
Finished piece of painted 12mm thickness of silk before the steaming process:
This is the finished silk painting on the seat of one of the dining room chair cushions: steamed, dried, cut and stapled onto the bottom of the seat cushion:
The second type of silk dye is set by heat only (simply pressing on the back of the painted fabric with an iron set to the silk setting). This type of paint is thick and requires a $13 bottle of formaldehyde based thinner which some painters might not desire because of the associated negative environmental factors.
Finished but not yet applied to the chair cushion: (note that the background is the natural color of the silk fabric):
Four more chair cushions to complete. I will continue using the dyes requiring the steam method. These cushions will NOT be matchy-matchy. For people with OCD, this might make you squirmy, but it is OK in this household.
