I found a new love in the quilting world - it's Aurifil’s Monofilament Invisible Thread, and it stitches like a dream. For years I've avoided invisible thread. It was never really invisible and seemed to always have too much shine for my liking. In addition, it was often difficult to use in some sewing machines - they just didn't seem to like it whether it was just in the top or, God forbid, you tried to put it in the bobbin. It was often too thick, too nylon-y, and reminded me of my Dad's fishing line.
But not any more!! (Trumpets blow here!) I've found a monofilament that really is invisible and stitches like a dream.
Aurifil's monofilament is made of a really fine nylon and available in two colors: smoke (for dark fabrics) and clear (for light fabrics). And trust me here Edith, it's a great choice whenever the thread or the stitching line needs to be invisible. It can be used for stitch-in-the-ditch, invisible machine applique, outlining, and free motion quilting.
For me, I can put the thread in both the top and the bobbin. (Again with the trumpets!) Your machine may be different and it may be more comfortable just using the monofilament as the top thread and using your usual thread in the bobbin: but I just lower my top tension and use a slightly larger stitch length. It sews beautifully! Aurifil suggests that the bobbin should be filled at the slowest speed possible and not completely. (It hasn't been a problem for me, but just passing on the info.)
Seeww, the next time you need an invisible thread try Aurifil's, it's pretty awesume. I think you're going to like it!
