@Bradley-Maker its no problem, now that the Forum knows what happened.
The issue for is that we need that Makerspace-marked SSP-donated material for doing the Kiln Room and Classroom renos, and the sheets are clearly marked both with green tape and edge marking. I notice you might not have realized there is the classroom reno to consider, as well, in your calculations of what material is required - for future reference, its probably best to check with key people who know the status of issues such as this - me, in this case, as the coordinator of the SSP donation and Kiln Room / Classroom install.
My understanding is that you will replace the Dave Holley sheet (if he wants) and the Makerspace sheet of formply with your own.
Members: please post to the forum when these kinds of moves are made so everyone knows what is going on. Also, check materials on all sides and faces for maker-marks denoting ownership/purpose prior to using them.
