CROCHET MUFF.   Godey's Ladies Book Feb. 1863 page 187        

Before giving directions for the muff we will explain the stitches.  For the fur stitch, pick up three stitches in one row, then three in under row, then three in the first row, and so on to the end of the row,  just as you would od Afghan stitch; you will have all the stitches on your needle.  Then make a chain of three and pull it through one stitch, then a chain of three and pull it through the second stitch, and so continue; this makes the fur part of the muff.

In Gobelin stitch you make the first row of Afghan stitch; then after that you pick up between the stitches instead of taking up the stitch.

To widen, you pick up between the stitches, besides taking up the regular stitches.
 

DIRECTIONS FOR MUFF  

The muff consists of two pieces, an outside and lining.

Set up with No. 5 needle 49 stitches with white zephyr for the under part of the fur, and work 53 rows of Afghan stitch.  In each stitch of white work one stitch of the fur (as we explained) with chinee worsted.  For the pink lining of the muff set up 41 stitches, and work in single Gobelin stitch 60 rows with No. 4 needle.

A piece of muslin with wadding is placed between the lining and muff; they are sewed together with a row of plain crochet, then a row of open crochet or holes, through which are run cords and tassels.
