Yes, please post a picture of the iron...I have one of those and fire scares me. I'm so sorry that this happened to you.
Once I found 3 holes in my backing fabric....they were about the size of a pencil eraser and spaced exactly 88 inches apart on the bolt of fabric. I solved that problem by appliqueing left-over blocks over the holes. Worked great and saved the fabric.
Sure hope your hand heals quickly.
