Glad the walking foot helped you manage the fabric, but it doesn't actually stop the curling. That foot just helps feed the layers evenly so the curl doesn't ruin your seam while you sew. The material will still curl up the second you cut it. For that, you still need to fight it with starch or pattern weights. The walking foot is a win for sewing knits, but it's a separate battle from the edge curl itself.

Gonna try that for your wedding setups? I used wet floral foam for a market stall last season and it kept everything perky for hours.

Yikes, my buddy Dave had his sauerkraut go totally nuts like that. It was in a warm pantry last July and got crazy fizzy, basically volcanoed all over his kitchen counter. He moved it to the basement where it was cooler and it calmed right down.
