hi, hi, sorry there! So busy these days - reading, writing papers, preparing presentations, and then there was that Thanksgiving dinner I made and now a tree and oh my goodness!
My work is done for the day, though, so let's see if I can't put a double dose out tonight. First off, some helpful links per your question, Jess: I honestly don't remember where I learned to embroider. I must have seen it in a craft book somewhere. All I know is that I learned the basic stitches a long time ago.
That said, here are two resources for getting started:
Adorn Blog has somewhat helpful images showing eight basic stitches at http://www.adornmag.com/node/14
However, the far more comprehensive (and beautifully explained) Stitch School over at Primrose Design will probably be more help. Have a look, Janet gives detailed instructions and step-by-step photos. Her website is http://primrosedesign.blogspot.com and Stitch School posts are linked in the right column.
In fact, I am currently embroidering the blue wool jumper that I made last month (shown above) with the Palestrina Stitch that I learned from Janet!
hope this helps!
