which mono thread are you using?
is it a polyester monofilament or nylon?
don't quote me on this because i have only my own experience as data.
the nylon seems to be stretchier, which could make tensions settings a headache.
more important, all my research indicates that poly is the only one we should use in any project that will feel the heat of an iron or dryer. nylon isn't as strong and can melt.
i did a bit of price checking before i settled on a brand.
all the poly mono-filaments are expensive.
i settled on the big cone sold by Superior threads.
so far i haven't had any tension issues regardless of what i put in the bobbin.
so i think i got a fair deal for what i spent.
