Common camera framing

Side profileClose-upOverhead

Description: Both partners lie on their sides face to face and interlace the legs alternately, so each thigh sits between the other's. The weave holds the pelvises together without either partner bracing, which is what separates it from the simpler crossed-thigh positions.

Variations: A full alternating weave or a single leg through; the top arm under the head, or wrapped over the partner's shoulder to close the distance.

On camera: The interlaced legs read clearly from overhead and badly from anywhere else, which is why it appears more often in illustration than in video.

AI design considerations: Four legs in an alternating stack, which is the single hardest limb arrangement in the catalog to render without fusing. Draw the weave order explicitly rather than letting the limbs overlap arbitrarily.
