Altering a stretch catsuit or leotard pattern is straightforward when you use the guide lines printed directly on the pattern pieces.
Katkow stretch patterns include reference lines such as the bust line, waistline, hip line, knee line, elbow line, wrist line, and ankle line. These lines help you lengthen or shorten specific areas without distorting the overall shape.
How to Lengthen or Shorten the Torso
If you need to adjust the torso length, cut along the waist guideline on both the front and back pattern pieces. Spread the pieces apart to add length, or overlap them to remove length. Insert paper behind the gap and tape securely.
When adding length for stretch garments, divide your adjustment evenly across the pattern pieces to maintain balance.
Adjusting Sleeves and Legs
Use the elbow and wrist lines to lengthen or shorten sleeves. Use the knee or ankle lines to adjust leg length. Always keep the cut edges parallel when spreading or overlapping.
Blending Between Sizes
If your measurements fall between sizes, blend smoothly from one size line to another. For example, you may cut a medium at the bust and a large at the hip.
Important for Stretch Fabrics
Remember that stretch garments rely on fabric elasticity. Always test your stretch percentage and sew a mockup when making major alterations.
Using the printed guidelines ensures clean adjustments while preserving the original design lines.
