I got about 250 China silkworm eggs and about 250 Zebra silkworm eggs earlier this year. (when I counted the worms after they hatched, there were over 600 worms.) They hatched and were doing very well on silkworm chow. Then the leaves on the mulberry tree (the only thing they eat) started coming out. I ran out of chow so started feeding them the early leaves.
By that time, some of the silkworms were spinning their cocoons. After a couple of days, the worms started dying. I ended up with about 200 cocoons. By researching I think the problem was that I fed them leaves that were damp. I should have dried them before feeding them. They were dying from bacteria. They are so delicate that it is hard to raise them sometimes. More information can be found on here:

I made hankies out of the cocoons that I had. I let some of them emerge and lay eggs for this next year. To make hankies out of cocoons: Put water in a crock pot set on high. Add washing soda and detergent. Put the cocoons in and let set until the cocoons get 'globby'. Rinse the cocoons in water with vinegar in it, rinse in fabric softener and then plain water. Gently pull the cocoon open and remove the pupa and stretch over an 8x8 frame. Keep adding until there is 10 to 12 cocoons. Take the hankie off the frame and let dry. After they are dry, they are ready to spin.
Pull one layer off. Put finger through the middle and start pulling into a roving. It is ready to spin. When I spun it, I just have to turn the wheel. It doesn't need anymore drafting. This part is very easy.
I decided that I don't mind playing with the silkworms but I don't like playing with the pupas. When the silkworms finish spinning their cocoons, they change into a pupa. At this point they have to be put aside to wait until they emerge or put in an oven and killed. I kept thinking about it when I was doing them and decided that I don't want to kill them anymore. I could let them be 'Peace silk' but I would have to do something with the eggs and I don't want to let them all hatch.
I feel two-faced because I still spin silk. I also couldn't kill a cow but I do eat beef. Life can be soooo hard sometimes.
I love silk. It spins nice and is very shiny. I have several pounds of silk roving. It is a dream to spin. I got it from Mountain Shadow Ranch in Pleasant Hill, OR. I also got some Mystery Batts from there. They are fun. They are a variety of fibers. They remind me of the fiber sandwiches I have heard about.
I'll get pictures posted of my latest work.
