HOW DO I FINISH A SCISSORS CASE

I’ve searched, I’ve posted, I’ve climbed mountains, I’ve gone down rabbit holes and no one will tell me or give me pointers on how to finish a god damn scissors case 😭 yes I can probably figure it out myself when I try again but considering y’all sell freaking scissors case canvases SOMEONE HAS TO KNOW. Please someone guide me before I butcher the ever living fuck out of my beautiful scissor case canvas. I’m not getting it professionally finished bc no one has time for that so don’t judge. HELP ITS A CHRISTMAS EMERGENCY
