Cam we have a custom recipie to turn created maps back into blank maps. This could be done using Blaze powder (used to undye glass/unstick pistons) and a map with any saved Id. I'm sure a lot of players have maps that were created with missing pixles or made in bulk a few too many copies to sell, or wish to reuse old irrelevant maps. This could be a great idea to support this suggestion.
Support! The number of times I have accidentally locked a mapart without realising that I missed a few pixels on the edge is embarrassing at this point, and I usually end up voiding them.
Bump... I have started a chest of maparts I have accidentally made/locked in anticipation of this being implemented.
Per my previous comment on Teeler's thread, bumping this suggestion again. Fun fact from today's Wikipedia featured article: On the flag of Canada, the number of points on the leaf has no special significance. The number and arrangement of the points were chosen after wind tunnel tests showed the current design to be the least blurry of the various designs when tested under high-wind conditions.
