Notions - Bohin Iron-Off Marking Pen # 91781 - White - is currently on backorder. You may still purchase now though and we'll ship as soon as more become available.
An air activated marking pen for drawing fine lines on dark fabrics. Marking appears spontaneously and clearly after five seconds. Markings disappear upon ironing or spritzing with water.
My favorite pen for drawing sashiko designs. It won't rub off - non-messy!
Always test any marker on a small piece of fabric before using. Some sizings may prevent the marks from washing or ironing out.
