Here’s a great tutorial from Wendi Gratz of Shiny Happy World for a stitch-of-a-thousand-uses. Wendi says,
Not only do I show you how to blanket stitch – I show you how to do it without any knots. No knots! So it looks perfectly perfect everywhere! And for those who are really obsessed with perfection, I show you how to mark the fabric before stitching so all your stitches are perfectly spaced.
