Maintenance of Finished Garments
Proper care of your finished corset will ensure its longevity and maintain its shape. Due to the inclusion of steel boning and various fabric types, specific care instructions are recommended:
- Cleaning: Dry cleaning is generally recommended for corsets with steel boning and delicate fabrics like brocade, satin, or velvet to prevent damage to the boning and preserve fabric integrity. If hand washing is necessary for specific fabrics, remove boning if possible and use cold water with a mild detergent, then air dry flat.
- Storage: Store your corset flat or hung carefully to prevent distortion of the boning. Avoid folding or crushing the corset for extended periods.
- Ironing: Use a low to medium heat setting and iron on the reverse side of the fabric, or use a pressing cloth, especially for delicate materials. Avoid direct heat on boning or grommets.
Troubleshooting Common Sewing Issues
While the Simplicity pattern provides clear instructions, common sewing challenges can arise. Here are some tips for troubleshooting:
- Fit Issues: Always create a muslin (test garment) before cutting into your final fabric. This allows you to make necessary adjustments to the pattern pieces for a perfect fit, especially crucial for corsets.
- Fabric Handling: If working with slippery fabrics like satin or shantung, use sharp pins, a walking foot, and a new needle. Consider using temporary spray adhesive or basting to keep layers aligned.
- Grommet Application: Ensure you use the correct tools for applying grommets. Practice on scrap fabric first to achieve a secure and neat application.
- Boning Insertion: If boning is difficult to insert, ensure your boning channels are wide enough and that the ends of the boning are properly capped or rounded to prevent snagging.
- Lacing: For smooth lacing, ensure grommets are evenly spaced and securely set. Use a lacing cord that is durable and appropriate for the grommet size.
