The first thing to consider in washing flannels so that they retain their size, is that the articles be washed and rinsed in water of the same temperature, that is, about as warm as the hands can bear, and not allowed to cool between. The water should be a strong suds. Rub through two soapy waters; wring them out, and put into plenty of clear, clean, warm water to rinse. Then into another of the same temperature, blued a little. Wring, shake them well and hang up. Do not take out of this warm water and hang out in a freezing air, as that certainly tends to shrink them. It is better to dry them in the house, unless the sun shines. They should dry quickly. Colored flannels should never be washed in the same water after white clothes, or they will be covered, when dry, with lint; better be washed in a water for themselves. In washing worsteds, such as merino dress goods, pursue the same course, only do not wring them hard; shake, hang them up and let drain. While a little damp, bring in and press smoothly on the wrong side with as hot an iron as can be used without scorching the goods.
Flannels that have become yellow from being badly washed, may be nicely whitened by soaking them two or three hours in a lather made of one-quarter of a pound of soft soap, two tablespoonfuls of powdered borax and two tablespoonfuls of carbonate of ammonia, dissolved in five or six gallons of water.
