| Sep 14, 2019 at 13:43 | comment | added | Xander Henderson♦ | @DarrelHoffman My first thought was, honestly, paint stirrers. However, these tend to be somewhat rough cut, and I am not sure that they would work well as a straight edge. They are also made of a pretty soft pine, and might not hold an edge for very long. | |
| Sep 14, 2019 at 13:35 | comment | added | Darrel Hoffman | Actually, this reminded me of the fact that most places that sell house paint will give away stir-sticks for free whenever you buy a can, which would make pretty effective straight-edges. This is only useful if you also wanted a bunch of paint, of course, so if you were planning on any home improvement in the near future, it might be something to think about. (They might also give you extras if you ask nicely, so you can get enough for the whole class...) | |
