Method
1. Cut your fabric: Fabrics can be cut to size/ shape before or after applying interfacing.
2. Smooth out the interlining adhesive side up (it feels slightly rough). Lay the fabric on top right side up with the grain lines aligned.
3. Cut the interfacing to the same size as the piece of fabric.
4. Place the fabric right side down on an ironing board.
5. Smooth the interfacing on top of the fabric, coated side down. Trim any interlining that exceeds the size of the fabric to prevent damage to the ironing surface, or lay on some scrap calico/ fabric
6. Cover with a smooth surfaced cloth; a tea towel or spare cotton are ideal.
7. Lightly dampen the cover using the iron's spray setting.
8. Adjust the iron to heat setting 3 – cotton, no steam.
9. Starting at one corner work the iron across the cover to lightly adhere the materials together, smoothing out any lumps or ridges as the iron moves across.
10. Lift the cover and check for any bumps. The fabric and interfacing may need peeling apart a little. Recover and lightly press.
11. Once the interfacing is smooth, dampen the cover again.
12. Press, spending 12 seconds on each area to achieve good adhesion.
13. Place the coated fabric somewhere flat to cool fully and set the adhesive.
