Casalguidi is the April challenge for stitch explorer. It's completely new to me, so I started with pulled and drawn thread embroidery. The first row is the hemstitch, the second row is the hemstitch again, but now I removed 4 threads. I secured those threads, with the help of this tutorial. The third row is the mesh stitch and the last part is done in waffle stitch. I altered it a bit halfway.
