So! I must have about 30 rolls of the stuff - in an effort to use it up, I've been taping up my shipping boxes with it instead of using packing tape. Alone, it's not quite strong enough for a large or heavy box, but what I do is I trim the half-page shipping label (I get these inexpensive labels from Amazon) so that it's tall and narrow, and the edge wraps over the side of the box, making a stronger seal at the top and bottom. It's a tuck-top box, so it's already pretty sturdy anyway.
And there you have it: washi tape instead of packing tape - as a bonus, you didn't use any plastic while you were making the packaging, so it's all recycleable or biodegradable.
