Many years ago, possibly forty, I embroidered a picture of goldcrests. I probably used a transfer pencil for the outline and then worked it in surface embroidery using satin stitch, long stitch and long and short stitch. I used a single strand of floss, very small stitches and lots of different shades. The result was very realistic birds. Of course my eyesight was much better then.
We have lots of tall conifers in our garden and we occasionally glimpse these tiny birds among them but they certainly don't visit our bird table.
When I was deciding what to stitch next in my blackwork garden birds series I thought I'd reproduce the same picture. It's interesting to compare the two. blackwork goldcrests
