I think French Séyès paper, the standard lined paper used by French students, is the perfect practice paper for improving penmanship. Gridded both vertically and horizontally and providing four narrow rules between each grid block provides space for ascenders, descenders and uppercase letterforms.
An assortment of sizes and formats of French-ruled notebooks from Clairefontaine are available through Writer’s Bloc web shop ranging in price from $2.85 to $13.50
