I've been scouring the internet for shikoro patterns, but so far the closest I've gotten is the side-on diagrams on Nihon Katchu Seisakuben. They're helpful, but they don't show the shapes of each lame laid out flat, which is what I'm after. Any of you know of somewhere I could get access to patterns like that?
Ben, Sorry I do not know of any published patterns, but they are not too difficult to work out. You don't say what type of shikoro you have in mind but either way, the first thing is to establish the shape of the upper row that fits against the koshimaki. I use a reasonably thick paper to establish the shape of the upper edge and to get the angle it needs to make with the bowl. If you think about it, by drawing the outline of the bowl on the paper when flat, it will fit the koshimaki but will stick out at right angles from it. If you now trim pieces from the front ends but leave the centre-back alone, the paper will start to assume a conical shape. Do that, slicing off a bit at a time, until you get the shape you want. Now decide how wide each row will be and draw a line parallel to the upper edge. Decide how much overlap you want and draw another line above the one you have just drawn - that is the upper edge of the next row. On hineno shikoro the shape of each row becomes more pronounced the lower you go, so you can modify the top edge slightly to do this. You then just carry on doing the same until you get to the bottom row which on a hineno shikoro is usually wider and has a deeper section at the centre-back and the front ends. It sounds complicated but it isn't and paper is cheap enough to keep going until you get it right. Ian B
Thanks a lot for the insight, that's really helpful stuff! Looking forward to trying it out. I was in fact looking at hineno shikoro when the thought occurred that I hadn't seen patterns for them, but it's good to see they're easy to work out. I'll definitely have a crack at making a pattern for one.
