Blocking Needlepoint Using Steam Method
This method is the saftest way to square your canvas. It can be used with silk, overdyed or other threads which may run.
To block, the first step for your canvas is mounting on stretcher bars. The canvas should be as straight as possible.
You should remember the following when steam blocking:
1. Use distilled or bottle water if you live in a hard water community.
2. Do NOT use a steam iron. These can spray droplets of water which can stain your fibers.
3. Test all questionable fibers for colorfastness.
4. Never over steam!
