Yeah on these ones I’ve found the single layer of moving blankets isn’t enough. I have this prefab one I use for when I’m hired to record other people in ad hoc spaces: https://a.co/d/0bY4Hliz I like the fabric it came with because it’s all sewn together as one piece and I just chuck it over the top; and then I use spring clamps to attach another layer of loose moving blankets. It gets wicked hot in there but does the trick for a modest amount of $$$ and sets up/packs down super quick. If you’re done spending $$, you can always hang clothes and blankets from the top frame so it’s more like a closet with baffles inside vs one open space.
