✂️ Finishing
Weave in all ends securely using yarn needle, ensuring no loose ends can come free during use. Block gently if desired by laying flat and misting with water, then allowing to air dry completely. Check all seams for security and reinforce any weak points. The envelope flap should fold over comfortably across baby's chest. The swaddle should be roomy enough for baby to bend legs into natural frog position. Never place baby to sleep with loose ties near face. This swaddle is designed for supervised rest and cuddling.
🧺 Care Instructions

Avoid fabric softeners which can reduce breathability. Inspect regularly for wear, loose stitches, or damage. Discontinue use if any safety concerns arise. Always follow safe sleep guidelines.
