Welcome!
This website was created by Piglet Evans and Matthew Simon Cavalletto to share our collection of charts that explore techniques for weaving potholders from loops. Read more about this collection.
The collection is available both as a single large PDF file and as individual charts that can be downloaded as image files from the list below. Items marked as “New!” have been added recently and are not yet included in the PDF.
There’s also an accompanying series of blog posts that include photos and commentary on many of the designs, as well as more general discussions of weaving techniques and pattern design.
How to Read Our Charts
Understanding a few common conventions used by the potholder-weaving community will help you understand how to read our charts.
These Charts are Free
This collection, and each of the individual charts, are available to everyone for free under an “open culture” license.
