I love the weaving program called Weave Design from Pikes Peak Weavers Guild! It is simply amazing to sit and design weaves on the computer. I love being able to eaily plan projects, or tweak small things in a project to see how it reacts before I put it on the loom. I have designed some twills on the computer before weaving them on my loom. It's a good way to allow your imagination soar without using up all your yarn supplies!
