And this is what we plan on doing to it. I can't get it close enough to me on the sofa so we'll try what I have typed in the photo's bottom. It may make it tipsy but I don't think so. We'll leave a space to allow the top to move freely without binding on the bottom.
While searching online I found lots of options for the type I want - sit on it. I saw some really nice ones but can't see how they would be secure just resting on my lap and I don't use a table. Do not like this one because the clamp is over the hoop, and to tighten it enough to hold it from moving, the linen would be pressed. But you have the option of using any hoop.
Lacis is online with JoAnn (coupon applies) and Nordic Needle also. Another brand name is also used but it appears to be the same piece. I like the way the hoop is attached but I would probably sit on it between my legs instead of the side. Depending on how big my thighs get, the hoop may not reach my lap. The dowel goes into the stand and can be turned to the angle you prefer before tightening. There should be other hoop sizes available to slide into the base but I haven't found them yet. Edit - just found them here in 12" and 14".
The second is handmade on Etsy from Kenhoops. Both can be adjusted for height but Ken's gives you more stability and angles. The base is heavier and wider, works with table or sitting. With the wing nut on the hoop, I think other sizes could be adapted and countersunk to accept the bolt. But will the wood on the arm right beneath the hoop edge be in the way? Nah. Pull the stitching down toward the center.
