Way back in the olden days, on a craft site far far away, I was involved in a swap. Maybe it was just a quilt block swap but someone had requested 3D blocks. And had a link to a sampler page with what I (probably incorrectly) remember having 12, or 24 different block patterns.
A lot of them were based on pleats and smocking techniques.
Does anyone have any idea what I’m talking about, any idea where to start looking, or the link?
That sounds interesting! A quick search brought me this textured quilt sampler, which seems to be the type of quilt you are looking for.
I started by searching 3D quilt blocks, which led me to search origami quilt block sampler, which led me to that page. Maybe searching origami quilt blocks or textured quilt blocks will help lead you to the specific sampler you are looking for.
