🧵 Assembly (Shortened Instructions)
Finish the lower edge of each triangle if desired for aesthetics. Attach binding to the inner bust edge, allowing slight overhang at top and bottom. Wrap binding over the fabric edge and secure using a stretch stitch or cover stitch. Trim excess binding ends. Attach long binding strips starting at the bottom outer edge, measuring up to the triangle tip per size, then secure and wrap to finish clean edges. Hem the bottom edge to create a casing for the underbust string. Insert the long underbust string through both triangles and adjust for desired spacing and shaping. Tie ends to secure. Full step-by-step instructions are included in the PDF.
