Once completed, most quilts are a bit wavy along the edges and even not quite square. That’s due to distortions from quilting, so even if you square up the top itself, the finished quilt may need squaring up too.
If the quilt will be washed often, such as a throw, baby or bed quilt, it may not need to be blocked. Washing will remove the blocking anyway.
However, “show” quilts and those that are to be hung can benefit from blocking. Wavy edges and other slight distortions will disappear and the quilt will hang perfectly flat.
Alex Anderson has created a short video that gives a brief overview of the “why” and “how” of blocking a quilt.
The following video from Shelley Sieverkropp goes into more detail about the blocking process. Her method is a bit more precise and shows another way to do the blocking.
Both Nadine and Shelley use a laser level square. This one is inexpensive and works nicely for quilts.
PLEASE NOTE: Quilting Digest has featured many patterns from vendors participating in the Craftsy Marketplace, most of which have been deleted by Craftsy. It's going to take awhile for us to hunt down new sources for those patterns. In the meantime there are many links to patterns on our site that no longer work. We apologize if this article contains one or more of those links and appreciate your patience while we straighten things out. Thank you!
PLEASE NOTE: Quilting Digest does not sell or otherwise provide patterns directly. We showcase patterns and projects from various vendors, bloggers and other sources. Please make a note of where you access a pattern (the link in the yellow box toward the end of each Quilting Digest article). That way you can contact Support for that source if you have downloading problems or other issues. Thank you!
