No. The printed lines do not wash out on Skillbuilders. We do not currently have the ability to print both permanent and temporary lines. The purpose of Skillbuilders is practice so one suggestion is to quilt it multiple times with different colored threads. You can also use a busy print on the back and then make a bag putting Skillbuilder on the inside (see the One Yard Tall Tote pattern in the Free Patterns and Projects tab). Because it is a learning tool, Skillbuilder doesn't have to look perfect and you don't have to keep it!
Thanks for asking,
