You lucky girl!!!
What scissor queen said ... a lot will depend on the type of silk. Some (Chiffon, Crepe de Chine, Charmuese for example) is very fine with gorgeous drape and hand but difficult to put through a machine (it slides around). Dupioni is usually nubbed, a little thicker. I've got some silk at home that is ribbed like coruroy that you woudn't guess was silk.
I've never tried it, but I have a friend who works with Chiffons a lot - for garments not quilts. She places masking tape over the seams to lend some "body" to the cloth and it is then easier to machine. As I said though, she's making garments - much larger and far fewer peieces to handle. So not sure if this is a viable option. Paper piecing might be viable but you still need to take care not to pull the fabric in any direction as silk has a lot more give even on the warp and weft.
So I would say wait till you see what she presents you with!! And have fun!!
And if you decide that you absolutely HATE it and must leave your sight immediately ... I'll foward my address :)
