Writing in an Old English style is a type of calligraphy, and it requires special tools and practice to do well. The fine motor skills and sense of geometry needed for calligraphy can be challenging.
Letters in an Old English style are usually Gothic or Blackletter fonts. These are serif fonts, with a mix of wide strokes and narrow embellishments.
A calligraphy pen has a flat end, or a chisel tip, held at about a 45-degree angle. The narrowest lines are drawn from top-right to bottom-left, and the widest from top-left to bottom-right. If a metal calligraphy nib and ink are too difficult, a felt tip pen with the correct shape may be easier. Spacing is important, and novices can use a pencil and a ruler to plan out a grid for reference.
