Oh yeah affixing to studs in the wall is a absolute must for this book shelf. I need to figure out what the angles are and the overall measurements. Make a template for the spider webs, rough out the spiderwebs with my jigsaw the use my router to finish the spider webs. Cherry burns so easy though... I'm going to need a new sharp bit and really slow router speed to pull off those spider webs.
Or I may just use my jigsaw to cut out the spider webs and call it done - since in the picture they aren't uniform anyways...
I might work in a French cleat to affix it to the studs. That way they can position it where the want.
