It can be 32 studs wide in one direction if it is longer than that in the other. Some qualifying examples would be 32x64, 38x38, etc. It could also be irregularly-shaped, as long as it fits the minimum dimension requirements. We don't really want to see 32x34 entries in this category. The idea is to go
BIG!.
If there are too many that are very nearly 32x32, we will likely increase the minimum size to something like 40x40 in future contests.
Keep in mind that there will likely be some really big entries, so if you want a chance at winning the unrestricted, you should probably do something bigger than 33x33, even though that technically qualifies
The border DOES NOT count toward your dimension size in the unrestricted category. For example, if you build a 32x32 entry and then put a border around it to make it 34x34, that doesn't count. The idea is that you are supposed to exceed a 32x32 MOC footprint.
For the FO/FL's sakes, it would be great if you would state the dimensions of your MOC when submitting so that we don't have to try to count studs.
