Stippling is really tiny....I think it may look better with more of a meandering. Also, a different color bobbin only works well if you are doing straight or slightly curved lines. If you are meandering or doing something with constantly changing directions, you have to use same color in bobbin or it will definitely show through. I was told that by many class instructors over the years. I like the suggestions of meandering or doing the zig zag on the stripes and then doing the scales look on the alligator. That will make the gator really stand out. FUN!
