His publications in the late 1800s were through Weldon & Company, a pattern company who produced hundreds of patterns and projects for numerous types of Victorian needlework
. Around 1888, the company began to publish a series of books entitled Weldon’s Practical Needlework, each volume consisting of the various newsletters (one year of publications) bound together with a cloth cover and costing 2 shilling/6 pence.
Weldon's Ladies' Journal (1875–1954) supplied dressmaking patterns, and was a blueprint for subsequent 'home weeklies'.
