Introduction
This instruction manual provides comprehensive guidance for using the Simplicity 1165 sewing pattern. This pattern allows you to create stylish and comfortable slim pull-on pants and shorts in two distinct styles. Designed for beginner sewing levels, the pattern includes options for two pant lengths and two short lengths, all featuring convenient pockets. The instructions are provided in English and Spanish, and the pattern was designed in the USA.
Setup and Preparation
Before beginning your project, careful preparation is essential for successful results.
1. Review Pattern Pieces
Familiarize yourself with all pattern pieces included. Identify the pieces corresponding to your chosen style (pants or shorts) and size. The pattern includes sizes 14, 16, 18, 20, and 22.
2. Choose Fabric
Select a suitable fabric based on the pattern recommendations. Lightweight to medium-weight woven fabrics are generally recommended for pull-on pants and shorts. Consider fabrics such as cotton, linen, rayon, or blends that offer good drape and comfort.
3. Take Measurements
Accurately measure your body to determine the correct pattern size. Compare your bust, waist, and hip measurements to the sizing chart provided on the pattern envelope. If your measurements fall between sizes, consider blending sizes for a better fit.

4. Prepare Fabric
Pre-wash and dry your fabric according to its care instructions to prevent shrinkage after the garment is made. Press the fabric to remove wrinkles, ensuring a smooth surface for cutting.
5. Lay Out and Cut
Follow the pattern layout diagrams for your chosen view and fabric width. Pin the pattern pieces securely to the fabric and cut accurately using sharp fabric shears. Transfer all pattern markings (notches, dots, etc.) to your fabric pieces.
Sewing Instructions
This section outlines the general steps for constructing your pull-on pants or shorts. Refer to the detailed instructions included with your pattern for specific seam allowances, finishing techniques, and order of operations.
General Construction Steps:
- Seam Construction: Begin by sewing the main seams of the garment, such as the side seams and inseams. Press seams open or to one side as indicated in the pattern instructions.
- Pocket Assembly: If your chosen view includes pockets, assemble and attach them according to the pattern. This typically involves sewing pocket bags to the front or side seams.
- Crotch Seam: Join the front and back sections of the garment by sewing the crotch seam. Reinforce this seam for durability.
- Elastic Waistband Casing: Create the casing for the elastic waistband at the top edge of the garment. This involves folding and stitching the fabric to form a channel. Insert the elastic through the casing, ensuring it is not twisted, and secure the ends.
- Hemming: Finish the bottom edges of the pants or shorts by creating a hem. Fold the raw edge up twice and stitch in place.
- Finishing Touches: Trim any loose threads and press the finished garment for a professional appearance.

Care and Maintenance
Pattern Care:
- Store pattern pieces flat or neatly folded in their original envelope to prevent creasing and damage.
- Avoid exposing the pattern to moisture or extreme temperatures.
- If pieces become torn, repair them with clear tape to maintain accuracy.
Garment Care:
Care for your finished garment according to the care instructions of the fabric you used. General recommendations include:
- Machine wash cold with like colors.
- Tumble dry low or hang to dry to preserve fabric integrity and prevent excessive shrinkage.
- Iron on a low to medium setting, avoiding direct heat on elastic if possible.
Troubleshooting Common Issues
Here are some common challenges encountered during sewing and how to address them:
- Sizing Discrepancies: If the garment does not fit as expected, double-check your body measurements against the pattern's sizing chart. Consider making a muslin (test garment) from inexpensive fabric before cutting into your final fabric.
- Fabric Handling Issues: If fabric is shifting or puckering during sewing, ensure you are using the correct needle size for your fabric type. Adjust tension settings on your sewing machine if stitches appear uneven.
- Pattern Alignment Problems: If pattern pieces do not align correctly, verify that your fabric was cut precisely and that all notches and markings were transferred accurately. Ensure fabric grainlines are correctly aligned.
- Elastic Waistband Too Tight/Loose: The length of the elastic is crucial for comfort. Measure the elastic around your waist and adjust as needed before securing it in the casing.
