Take a sufficiency of dry starch, very finely powdered, and sift it, through a fine sieve, into a broad, clean, tin pan. Set the pan near enough the fire for the powdered starch to get warm, stirring it frequently. Then roll and tumble about the white fur among the powdered starch, till it is well saturated. Shut it up closely in a bandbox, and let it remain unopened for a fortnight. It will then look clean.
When you put away white fur in the spring, proceed as above, (using a very large quantity of the pulverized starch,) and put into the box some lumps of camphor tied up in thin white papers. Keep the box closely shut through the summer, and do not open it to look at the fur till you want it for cold weather. It will then be found a good clean white.
In joining pieces of fur or swans-down, lay the two edges together, and pass the needle and thread back and forward on the wrong side, (in the way that carpet-seams are sewed,) so as to unite the edges evenly and flat without making a ridge. Then line every seam by sewing or running strong tape along it, of course on the wrong side. Unless they are strengthened in this manner with tape, the stitches are liable, after a while, to give way, and the seams or joins to gape open, making rents inside that are very difficult to repair.
