Huh. They are. Never heard of them before. Really, really nice selection.
I've got this massive machine applique project in front of me and I keep putting it off.
When you used the Invisafil in the bobbin, what were you using on top? A heavier weight cotton?
Did you match the bobbin color to the top color or use a neutral?
Although I see there isn't a huge color selection for that particular thread.
Thanks for the information.
