Where these curtains are used
Workroom and manufacturing notes
- Fabrics are checked and cut carefully before making.
- Made in UK workrooms to contract-grade standards.
- Standard made to measure curtains are made at 2x fullness (100% fullness) for a pleated finish.
- More detail: curtain fullness.
Delivered pulled and hooked
Your curtains arrive pleated to your track width, folded neatly, with hooks already inserted. You only need to clip them into your track or pole.
Seams on wider curtains
Wider curtains may require joined widths of fabric to achieve the finished size. Widths are rounded up to the nearest full width, so a joining seam can be present on larger curtains.

First class company to deal with.We recently had new curtains made by Direct Fabrics for our village hall, and we’re really happy with how everything turned out. The whole process was smooth from start to finish. The team were friendly, easy to deal with, and gave us helpful advice on what would work best for the space. The curtains themselves look great and feel really well made—they’ve made a big difference to the hall. Initially there was a problem with the fabric we chose and we had to wait for a fresh batch, the communication was first class during the wait and our order was prioritised once the fabric arrived. I would definitely recommend Direct Fabrics.0 people found this helpful
