I am making monogram soap for my sister and purchased a mold that has a raised letter and a beading pattern around the edge. I have tried using a plastic pipette to fill the letter and beading but find that the pipettes tip is curling which makes placing the colored soap most difficult! How does everyone else color details in soap molds? I may have to purchase glass eye droppers but didn't want to spend the extra money if I didn't need to. Any thoughts/suggestions would be most appreciated!
