Wow! It's fun to get out the extra fine tip for your electric kitska and really go nuts on some chicken eggs. Look at the detail you can achieve! It's nice when you are trying to carefully wax in small triangles and draw netting that is really fine without blowing the corner of a tight triangle or running the lines together and blurring everything. It is easier to use your extra fine tip with an egg that is relatively smooth on the surface, like a pullet, chicken or duck egg. It's a little trickier on a goose egg with some of the small bumpy surface area- but you can achieve it by taking it slowly, allowing the wax to come out in a nice solid bead. Be patient! It's worth it!
