I had the grand idea of making a canvas cover for a box. I had envisioned installing a long zipper that would go around 3 sides of the cover. I installed the invisible zipper w/o much ado but when it was time to test for closure. The zipper will not go thru the corner. How do I correct? If you can point me to a tutorial I will greatly appreciate it.
First pic shows invisible zipper sewn along 3 sides
2nd pic shows where it closed to end of first side but can turn corner. What did I do wrong, can I correct?
Hope this is clear
