This is actually on pale blue fabric, although the background looks white in my pictures!
Here are the stitch details for this project. The trees are all done with layers of Lazy Daisy Stitch. I combined two threads of pale green with one thread of white to give a snowy effect. The holly leaves are Fishbone Stitch. The holly berries and the roof lights are French Knots.
*The Straight Stitch was not a good choice for the eave accents. They are too long and now that this project is out of the hoop, the long Straight Stitches are too loose and shift out of place when I handle the fabric. To correct this, I am going to couch them into place.
