RECEIPTS FOR TWELVE CHAIR COVERS, IN DIFFERENT PATTERNS.
Most of the patterns have been test knit and updated with gauge and size information and those can be found at http://knitting-and.com/wiki/Category:Exercises_in_Knitting
The original book provides no gauge, yardage, or finishing instructions. Typical of Victorian patterns, it is assumed that the knitter will figure things out, including errata.
The entire book can be viewed on the Gutenberg.org website. The book is a project being recorded and knitted by volunteers at the Librivox site.
