Our 2019 Wooly Block Adventure pattern features a heart with a key on a string. We embellished our heart with stitching. The key can be made with wool or through stitching. An optional Patchwork Garden kit is available which includes the pre-cut and pre-fuse heart and leaves, along with the background wool.
