Blanket Stitch looks like continuous Kloster Blocks but with an outer edge, and is stitched using the same size thread. Use the small piece of 14ct to practise before starting the bookmark.If your stitching is a stitch over or under in width, your bookmark will fall apart when you cut the edge. The outer corner can be quite tricky to keep on line so it may help to practise first.
Blanket stitch is best worked clockwise as the corded edge lies more evenly; the chart instructions highlight where to begin stitching.
To begin come up the hole before your first stitch, shown above as a diamond. Go down the inner (open) side (1) of the next stitch and up the outer edge (2).Your thread must wrap round the needle to make the corded edge. Continue by going down at (3).
To form an outer corner, blanket stitch as normal but use the same inner hole (A), changing direction after 5 stitches. You can check the corner is correct as the new direction should have the same thickness of stitch (over 4 holes).
To perform an inner corner, blanket stitch as normal and use the outer hole (A) again for the edge of the new turned stitch. You need to come up to the left of your thread to form the wrapped edge.
Cast on and off the same way as for kloster blocks. To finish a thread, loop over the outer edge of the last stitch and go back down the same outer hole; cast off. To begin a new thread come up the same outer hole but to the left of the stitch, your thread will then wrap over when you begin stitching.
This is how your blanket stitch and corners should look. The lower stitching (two colour) shows how the start a new thread.
This is how your stitching should look on the reverse. You can use the back to check you have not gone off line at the outer corner - this can easily happen as the stitching is close together.
