Product Information

Full details

The Prym Forming Tape - 12mm - Anthracite is designed for sewers and crafters needing to create neat, durable hems on curved or diagonal fabric edges. Its key benefit is providing a stable, fusible edge that prevents stretching and ensures a professional finish. A potential consideration is its polyester composition, which may not be suitable for all fabric types or heat sensitivities. This tape is a 100% polyester, 12mm wide, 5m long forming tape available in white or anthracite, ideal for hemming rounded and diagonal cuts.

FAQs

What type of fabric is this tape best suited for?

It is best suited for woven fabrics and certain stable knits that can withstand ironing temperatures. Always test on a fabric scrap first.

Can I use this tape on very delicate fabrics like silk or chiffon?

It is generally not recommended for very delicate or heat-sensitive fabrics. Test on a scrap first, and use the lowest possible iron setting with a pressing cloth.

How long does the hem last after applying the tape?

The bond is durable and designed to last through regular wear and washing, up to 60 degrees Celsius.

What is the difference between the white and anthracite versions?

The difference is the color. The anthracite version is a dark grey, designed to be less visible on darker fabrics, while the white version is suitable for lighter materials.

Do I need to pre-wash the tape or fabric?

It's always a good practice to pre-wash your fabric before applying any interfacing or tape to prevent shrinkage later. The tape itself is washable up to 60 degrees Celsius after application.

Can I use steam with my iron when applying the tape?

Using steam depends on the fabric. For most fabrics, dry ironing is recommended for fusible tapes. If using steam, ensure your fabric can handle it and test first, as steam can sometimes affect adhesion or fabric texture.

How do I remove the tape if I make a mistake?

Removing fusible tapes can be difficult and may damage the fabric. It's best to try to apply it correctly the first time. If removal is necessary, gently try to lift the edge with a seam ripper or a warm iron and pressing cloth, but proceed with caution.

Troubleshooting

Tape not adhering properly

Ensure the iron is hot enough for the fabric type. Press firmly for the recommended time. Check that the fabric surface is clean and free of lint or sizing. Make sure the tape is placed correctly on the fabric.

Fabric becoming distorted during application

Do not stretch the tape or fabric excessively during ironing. Use a pressing cloth. Ensure the iron is not moved around too much; use a steady pressing motion. Try a lower heat setting if the fabric is sensitive.

Hem looks bulky

Ensure the tape is centered correctly within the hem allowance. Trim excess fabric if necessary. If using on very fine fabrics, consider a narrower tape if available or a different hemming method.

Tape shows through on the right side

Ensure the tape is fully covered by the fabric fold. Adjust the hem depth or use a slightly wider tape if this persists. The anthracite color might be more visible on very light fabrics; consider the white version.

Setup, Compatibility & Care

  4. Cover with a pressing cloth or the fabric's reverse side and press with a hot iron (refer to fabric care instructions for temperature).
