So you just have to get yourself some great fabric, watch the video instructions on You Tube and you are ready to go. None of my patterns are multi sized so there is one size per file, this saves a lot of paper and confusion as to which line you have to cut. Every pattern is hand drafted and then imported into a CAD program to make sure you have a pattern that fits and looks good too! No pattern is automatically graded or computer generated with software. Having trained as a tailor 30 years ago I know that pattern generating software can never replace the skill of a pattern drafted by hand. Try my patterns and you will love the fit. No loose armholes that are cut too low or sleeves that hang of the shoulder. The pattern pack includes: A pattern in PDF format ready to print on regular US letter size paper with assembly instructions Detailed video instructions on You Tube https://www.youtube.com/watch?v=ccFSVBJ6lFY Fabric requirements No serger is required to make this dress.
