Single size patterns are easier to use.
There are several reasons to make more than one size of a garment. Perhaps you are outfitting a choral group or you want to continue to use a pattern after a child has grown. Patterns can be expensive, so it is worth spending the time to trace a multiple size pattern and cut out a single size pattern for every size you will need.
Instructions
1. Cut the tissue paper pattern apart to separate all the pattern pieces. You may not need every pattern piece included in the envelope to create your garment. Consult the instructions and set aside any pieces you do not need.
2. Lay thin interfacing, pattern fabric or transparent paper over the largest piece of the pattern. Starting with the largest piece allows you to use the leftover scraps of interfacing or paper for the smaller pieces.
3. Pin the tracing paper or interfacing to the pattern in two opposite corners. Place the pins in blank spaces on the pattern.
4. Trace the cutting lines that correspond to the largest size with a pencil. On some patterns, the cutting lines are drawn differently for each size. One size will have a solid line, one a dotted line etc. On other patterns the size is written beside each line.
5. Trace the seam lines, darts and other pattern markings that correspond to that size. Also trace any marking that apply to all sizes.
6. Remove the pins and trace over the pencil lines with a ballpoint pen to make them easier to see. You will be cutting out the piece along the cutting lines, if they are easy to see you only need to trace the other markings.
7. Write the name of the pattern, the name of the piece, the size and other notes on the piece. For example a piece might be labeled, "Bishop dress, Long sleeve, Size 4, Cut 2 on fold."
8. Cut out the pattern along the cutting line.
9. Trace the next smaller size of the same piece, label and cut it out in the same way. Continue until all the sizes of this piece are made.
10. Trace the other pattern pieces in the same way; working from largest to smallest.
