I am also going to do one for my mother-in-law. Sandy suggested cupcakes. That will be fun!
Silk requires a lighter touch and a leap of faith. You draw the image with a gutta resist and then apply the dye with a brush and let it flow. It blends to the edges of the resist and stops (unless the resist has a leak!).The colours can be mixed right on the silk or in little glass cups. Over painting, too many strokes, letting part dry and then going back in causes blotches and ugly spots but sometimes they can be fortuitous if you are willing to play and take a few risks. Once the image is completed the silk is carefully wrapped in newsprint and placed in a container (a canning pot is good) so it sits over water that is brought to a simmer. A solid lid that holds the steam in is necessary. The steaming goes on for about four hours to set the colour. The results, if there are no problems with water touching the silk and unexpected "bleeding" of colour, are
spectacular - vibrant and satiny. Glorious.
