This is why I stopped responding to the inquiries about costumes. Look where you all are taking this, except for you Laura, who in my mind knows her stuff and knows it very well. I love your site and your work. I draft my own patterns, why, becuse I have taken many classes in both design and pattern making. This is not an easy thing to do. Please Krystyna, listen to Laura and take her advise on both the patterns she uses and the methods of construction she has so freely given on her website. You can't go wrong. Laura's website has taught me things that even my instructors could not help me with. If you are as lucky as I have been and you continue with your sewing classes you may run into an instructor who has worked in lycra and knit fabrics. These fabrics are a totally different animal when it comes to sewing, it takes time and patience and I am sure Laura will agree with me on that. Good luck
