I remember 'growing' them when I was a kid and I would like to share that

later in the year when the mulberry trees have grown a few more leaves.

You do know that silkworms don't REQUIRE mulberry leaves, do you?
I just forget most of the alternatives, but I think lettuce leaves
are one option. Different leaves result in different coloured silk.
While mulberry leaves lead to golden thread, lettuce produces white
silk, IIRC. Or that's the general idea, anyway. Might be handy if
you don't have a good supply of mulberry leaves.
