@ef8a8b60 This was four gouges. A 5 sweep 30mm for most of the curves, a 5-14 for leveling the background, a 7-20 for the tighter curves nearer the middle, and a 2-6 (a quarter inch skew) for detail work and getting into the corners. And a chunk of wood. But a triquetra like this had some tricky bits. Start with some simple stuff like thumbnails or an S-chain, and it’s pretty easy. The only workholding was a small table to raise the work 6-8 inches above the bench and hold it in place. 

 @ef8a8b60 Karvsnitt, from Lost Art Press had a number of patterns and ideas I ended up incorporating into this bench I’m working on. But that uses a knife-based method of carving, whereas I use gouges more. But the ideas are all similar. https://lostartpress.com/products/karvsnitt-carving-pattern-color-in-the-slojd-tradition

Chris Pye’s “Lettercarving in Wood: A Practical Course” is also highly recommended. I did the edges of this similar to the way Chris teaches you to do letters, and overall, that’s more my style than the slöjd-based style of Karvsnitt. 

 @ef8a8b60 I also used Ron Aylor’s “Categories of 17th Century Mannerist Carving” as a source of ideas. https://books.apple.com/us/book/x/id1490924385 (from https://ronaylor.wordpress.com/ebooks/ is you don’t have an iOS device). Ron is a friend (who I’ve never met in person), and I’ve picked up quite a bit of carving know-how from him over the years.
