Its Sew Emma 蝸牛小徑 12 英吋區塊基礎紙

I love how the shaded and numbered templates take the guesswork out of paper piecing—my first block came out perfectly straight. It's so satisfying to see the snail trail pattern emerge without any fuss.

I’ve made four blocks so far and the shaded sections really help me keep my place when sewing. The paper tears away cleanly without snagging my stitches.

The shaded numbering made my first Snail Trail block come out perfectly flat—no puckering at all. I’ll definitely be buying another pad for a throw quilt.
