40x34inches- The bold combination of harvest orange, avocado green, and bright yellow was iconic during that decade, particularly in handmade "afghan" blankets and knitwear. If this is an authentic vintage piece, it was likely handmade during the 1970s. If it is modern yarn or a contemporary project, it uses a nostalgic '70s throwback aesthetic. The stretchiness comes directly from the garter stitch (the ridges you see in the blocks). Garter stitch creates a highly elastic, squishy fabric that expands easily in every direction. I believe this is made with Superwash Merino Wool.
