This small wall hanging was made in 1995 for my sister-in-law Ashley who has Scotties. I used an appliqué pattern from a magazine (have forgotten which one). Each dog is from a different black fabric which is fused to the white background and then machine zigzag stitched in place.
Here are some sources for Scottie Dog quilt patterns:
