Tulle needs no seam finishing at all, which removes most of the work. It is a net: it cannot fray, so a raw edge is a finished edge.
Use a 70/10 sharp or microtex needle and fine polyester thread. Heavier thread sits on the surface of the net and shows.
Lengthen the stitch to about 3 mm. A short stitch perforates the mesh into a line of weakness, and on tulle that means a seam that tears along the stitching.
Reduce top tension. There is almost nothing for the thread to lock into, so ordinary tension pulls the seam tight and gathers it.
Hold the layers with clips, not pins, which snag and pull threads out of the net. On a multi-layer skirt, baste the layers together at the waist and treat them as one.
It does not press. Most tulle is nylon or polyester and melts on contact with an iron. If a crease must come out, hang the garment in a steamy bathroom, or hold a steam iron well clear of the surface.
Gathering tulle is easiest with two rows of long machine basting in the seam allowance, or by feeding it under a gathering foot. Because it does not compress, layers add up fast — a gathered tulle waist can become bulky enough that the machine struggles.
Cut it on a large surface. Tulle slides off tables and drags itself out of shape while you cut.
Questions people actually ask
Do I need to finish tulle edges?
No. It is a net and cannot fray. Raw edges are standard on veils, petticoats and skirt layers.
My tulle seam is gathering up.
Top tension too tight and the stitch too short. Loosen the tension and lengthen to around 3 mm.
