Here three examples of latvian patterns found on various pages and reproduced with seizenn pattern editor.
I’d like to share with you a question about the interface of the editor.
In plain mode, interface is easy. You click on an hexagon to change its color.
For pickup it’s a bit more complicated. In fact when you do a pickup, a thread that should be underneath goes above the band.
On the page aspinnerweaver.blogspot.com/p/resources.html, there is a link to a Norwegian Pick-up Bandweaving tutorial (norwegianpickupbandweaving.com/2015/05/12/pattern-design-basics/)
