This foundational template contains no design elements, style lines, or seam allowances, representing only the exact dimensions of a specific body or standard size. Patternmakers trace it to develop new styles, adding ease, darts, and seams as needed. Having an accurate block eliminates the need to adjust fit from scratch for every new design.
Once we get the bodice sloper approved on the fit model, we can draft the new fall blouses.
Always transfer your sloper to heavy tagboard so you can trace around it hundreds of times without wearing down the edges.
