In the waste canvas tutorial in a previous post, I mentioned that fractional stitches could be accomplished but did not elaborate. Since I was doing just that this afternoon I thought I would take this opportunity to illustrate what I meant.The waste canvas is made up of pairs of threads. In most cases, you treat the pairs of thread as one thread as I have done using the silver metallic thread above. However, if you want to make half or quarter stitches, you can divide the pairs of thread to give you a middle space. If you click on the above picture, I hope it will be clearer and you can see that is what I have done with the stitches in the gold metallic threads above.
Here is this motif finished after the waste canvas has been removed. It is one of several lovely blackwork motifs in The Cross Stitcher's Bible by Jane Greenoff.
