Personally, I like using different fabrics for ties. Things like denim or corduroy make great ties, while being a bit different from the run-of-the-mill store-bought tie.
Additionally, silk and silk imitation is slippery and tricky to work with. If this your first tie, consider an alternative fabric that is more forgiving.
The lining of the tie is the bit that is used at the tip to cover up the back. If you are not sure what I mean, look at the back of the tip of an existing tie. See that rectangular patch of fabric you can see there? That is the tie lining.
Your tie lining will add an extra fabric inside a part of your tie. So it is important to avoid bulk. Go for something thin, even when using a thicker tie fabric.
Your tie interfacing is the skeleton of your tie. It is the part that sits in the middle and that you will only see while constructing your tie.
Tie interfacing can be notoriously hard to get. The best tie interfacing is soft, fuzzy woven lambswool, but I have yet to walk into a fabric store that carries this.
Mientras mantengas tu corbata lejos de las tijeras y de los fanáticos del bondage, tu interfaz de corbata durará sin esfuerzo tu corbata. Así que mira en tu armario (o en la tienda de caridad/tienda) para ver ese viejo empatado con la mancha en él, y tomarlo aparte para salvar la interfaz de empate.
