- Pattern Generators where you put in your measurements and it tells you how to draft the pattern for your size. much like the Elizabethan Corset Pattern Generator.
- Drafting instructions that tell you to take certain increments of your measurements to make the pattern shapes.
- Premade patterns for download on a scaled pattern sheet that do not have seam allowances, but you have to scale them up.
- Premade patterns for download that are full sized, but on several sheets of paper so you have to tape them all together. If seam allowance is included it is marked by a dashed line, where as the cutting line is solid.
Now I personally am good with math and drafting, but I know many who sew who loath math.
The pros & cons of each of these different methods is
- The math is already figured out for you! you print out the instructions, grab your paper, ruler and pencil and draw as it says to. Custom fit.
- Lots of Math involved, if the instructions aren't clear, newbie (or those not good with math) will get lost. you print out the instructions, grab your paper, ruler and pencil and draw as it says to. will take longer. Custom fit.
- no drafting involved. Must scale up the patterns, either by hand or machine. sometimes things will not line up correctly. then you have to add seam allowance. "standard sizes" you must adjust to your own measurements.
- No drafting involved. must tape several sheets of paper together, things may become misaligned during this process. "standard sizes" you must adjust to your own measurements.
