Pattern instructions:
For the front and back square:
Cast on 50 (52, 54) sts.
Work in Garter Stitch until the piece measures 14 (15, 16) inches. Bind off.
For the turtleneck:
Cast on 50 (52, 54) sts. Work in Garter Stitch until the piece measures 8 inches. Bind off.
Sew the pieces together at the top, joining 3 1/2 inches on each side to create the shoulder seams. Next, fold the sweater in half and sew the side seams together, leaving a 6 (6 1/2, 7) inch opening for the armholes. This simple construction gives the sweater its relaxed, poncho-style fit while keeping the assembly beginner-friendly and easy to follow.
Fold the remaining piece in half lengthwise to create the turtleneck collar. Sew the short side seam together to form a loop. Then attach the turtleneck to the neckline of the sweater, sewing evenly around the opening. Once attached, fold the collar over for a cozy, relaxed turtleneck finish.
