Step-by-step instructions for drafting a basic Back body block, for a front, back or side opening garment.
Doesn’t include the style lines or seam allowences, those come later in the process.
These instructions use the Measurements Checklist (PDF) sheet. Please download it, print it and fill it out before attempting these instructions.
- Paper is cheap, don’t cut too small a piece, typically half the chest measurement plus seven inches is a good size. This should be big enough to draw both the front and the back on the same piece of paper. You can also draft the front and back on their own individual sheets
- Leave yourself enough room around the edges of the paper. Start 3″ from the side edge and 4″ from the bottom, square off and draw guide lines for the edges of the body block. Leave more room if your bodice has a point, other waist treatment or if it goes down to your hips.
- Measure accurately; Use your L or T square to draw true straight lines. Anal retention to detail is not always a bad thing, especially when it comes to drafting.
