WRINKLING, CRINKLING, ETC.
These are caused by putting on a too heavy coat of varnish, or by not dressing it out and wiping it up properly; also by using a varnish not sufficiently ripened. A varnish which shows wrinkling or crinkling while standing in a warm room may be made to assume an aggravated form of the trouble by simply transferring the work to a cold apartment. In the case of varnish wrinkling or crinkling, methods of prevention are preferable to any system of cure.
