I have 3 scars on my left arm that turn red when I'm drinking or when I work out. They're big scars. Well one is a 1.5 cm horizontal scar in the middleof my forearm, another is 3.5cm along my thumb, and the other one is about 13.5 cm long starting from the tip of my elbow up all are surgical scars. I want fake stitches on my arm like patchwork. Like a zombie. Or like Frankenstein and I want my scars to look like the stitches split open. I also already have an inverted pentagram tattoo on my left forearm 7cm big. On the inner part below the bend of my elbow I want that scar to look like it was patched on
