a. To preshrink dry-cleanable fabrics use a steam iron and move the iron horizontally or vertically across the grain of the fabric (never press fabric diagonally as this may distort the fabric).
b. Put colour fixer, (a number of brands are available in the market or can be fixed with a home mix of a table spoon of salt and half a cup of vinegar in half a bucket of water) in the same water in which fabric is soaked.
c. For correction of off-grain fabric, pull it diagonally at the opposite ends. First in one direction then in the other, this process is also known as blocking.
