Size: 18mm hexagons per side Paper: New V Matte NA 186.1g/㎡ (about the thickness of a postcard) *This is recycled paper with printing on one side. It should not affect usability, but there may be slight smudges on the white side depending on the printer. Since the core paper is unused, it is listed as "new, unused." 1150 sheets = I think this is enough for 96cm x 96cm. A 1/4 scale layout diagram is included (A3 size, regular OA paper). (Please note that the thickness of the fabric will be added around the core paper.) I made this because the backing paper was wasteful. Please forgive some errors due to hand-cutting. #PatchworkQuilt #CorePaper
