Grandma here, dear. First thing you’ll want to do is think of that wall like a warm knitted blanket—layer it. Start with a strong, sturdy base of well‑finished stone or brick, then lay a thick mortar of lime and sand, because lime gives that old‑world flexibility and breathability. After the mortar sets, you can add a second layer of smaller stones or even a few rows of lime‑mix bricks to fill any gaps. If you’re really looking for that blanket feel, tuck a row of tightly woven wicker or oak slats in between the layers, then cover them with a weather‑proof membrane. That keeps the moisture out but lets the wall breathe. Remember, the key is patience and a little love—just like when I stitch my shawls. Good luck, darling!
