Drafting Tape or Artist's Tape
Which you should have anyway.... essential tool for every one using paper for artwork.
"Drafting Tape" looks ordinary masking tape, but has a far less adhesive glue, so it pulls off clean and comes off really easily, will not pull off paper.
My choice: "Artists Tape"
It's a smooth finish white papper tape, slightly stickier that the drafting tape, still FAR LESS sticky than ordinary masking tape. It's for use with paints to achieve a nice sharp edge because it grabs the paper grain better (use it for your everyday scribal work, double duty...) The adhesive still pulls off just as clean, but it also looks NICER stuck on things, people won't think it's ordinary masking tape which is what the drafting tape looks like, and they will wonder about you using masking tape on a scroll. This is all I ever used.
You can also spot mount it at the side and corners using drafting dots.
