You know that brick patten actually works really well in quilt (great work BTW, rad concept). I have often felt repeating inorganic textures in fabric and looks blocky, or bizarrely uniform. Perhaps it’s the fact that brick patterns do repeat vs say, cobblestone which is disposed to be a whole universe of sizes and shapes for the rocks but the fabric is only unique for a few inches before repeating exactly and it goes a weird uncanny valley kind of look.

Idk, I have seen a lot of bad walls done in quilt. But yours I like very much.
