smileabit, which pattern & instructions did you use? Suzanne's & Dani's instructions are well worth purchasing. I learned to make stretch tutus from the no longer available treasure trove of tutu construction on The Sewing Forum ( The Place's previous site) - mostly contributed by Dani, Suzanne & many other experienced & talented tutu makers. Yes, I purchased Dani's patterns and instructions but most of the instructions were already on the site but spread across a multitude of threads - I'm certain that I read and made notes on them all. This site gives a good and probably clearer instructions than I could manage
Tutu Tacking. I would recommend steaming even with an iron but be careful not to melt the netting or burn yourself. Steam on a flat surface. If she's patient, I would suggest getting your daughter to wear the tutu while you tack. She needs to stand properly. You can manipulate how it sits and she can hold the top layers out of the way. The rule of thumb regarding bounce is that when she stops, the tutu stops. I suggest getting her to jump on occasion to make sure that the tutu is behaving as wanted - and adding more tacks if necessary. The tutu should slope down slightly to cover the pants. I used upholstry thread that matched the net. I used individual hand tied tacks - it takes a long time.
