A couple of years ago, I bought a set of stamped cross stitch pillow cases. This was before my daughter became a teen and she still wanted to do what Mom was doing. She put in about 5 stitches and the pillowcases have been sitting since.
Here is the picture of the pillowcase that has been started:
I will have a visit from the frog (rip it rip it) this evening! It is filling in the shape but doesn't have nicely uniform chain stitches that I want to see.
I have been researching chain stitch and there is a lot of information available on line. Wikipedia has an entry on Chain Stitch which is complete with pictures and diagrams.
A good place to see the stitch being made is at Needle N Thread. The Embroidery Stitch Video Library is impressive! You can find the video for chain stitch here. Another resource is Sharon b's Dictionary of Stitches for Hand Embroidery and Needlework. The Chain Stitch entry can be found here. A third resource could be Needlework and Embroidery tips and techniques from Carol Leather. You will find her entry on Chain Stitch under Surface Embroidery Stitches.
