Please note that usually the sheet sizes are approx 9x12 inch and roll sizes are 12x54 inch. In some holographic patterns the "print line" created during manufacture of the vinyl (where the design starts and stops during printing) can be visible. It is not a fault and refunds/replacements will not be issued if your order contains some holographic that has this. This is not adhesive or HTV.
Some vinyl types are not suited to heavy stitches like a satin stitch, it is always recommended to do a test area first before commencing your major project.
