It looks like the linen thread has bad spots that just will make it impossible to work with. It's not one of yours -it's some hand spun stuff I bought many years ago. Because it's hand spun, the width changes which probably is part of the problem. So, no, not one of yours. :-) The silk is but I know that's good stuff because I've used a lot of it before. Hence, why I'm switching from one to the other. I just really, really, don't like switching threads with different contents like that. It's a silly thing, I know, but if I start with a linen thread, I want to finish with a linen thread.
