This month's stitch, chosen by Marilyn, is Running Stitch. While it is a very simple stitch, it can be used in many effective ways and variations.
Peregrine Blue on Flickr has used running stitch in a very simple manner on this collage to add texture.
Running stitch can be pulled or drawn, causing the fabric to ripple in an interesting way, as with the above closeup of Peregrine Blue's collage.
It can also be used to build up a picture, as in this elephant, also from Peregrine Blue.
Luci F has used simple running/straight stitches to emphasise parts of this printed design, adding texture.
Lovefibre used running stitch to form a resist on these pieces of fabric before dyeing them.
They've come out fantastically - she has more photos on her photostream.
Another great use of running stitches is in traditional Kantha work. For an interesting take on Kantha, see this post on Linda Kemshall's blog.
You could also try a seed stitch, lots of running stitches scattered over a surface. I've used them in a very regular fashion on the top of this piece.
How about whipping or interlacing a line of running stitch? You could vary the thread you use for the whipping or interlacing, to add variety. We'd love to see what you do with running stitch, you could post pictures on our Facebook page, or bring things along to our next meeting.
