Hey there! Yeah it's sometimes slow around here, but there are several of us that post around here often. I think from the looks of it, you are needing a double pouf tutu. I'll try to explain it as best as I can:
1. find out your waistband measurement and subtract 5 inches
2. sew together a strip of non-roll elastic measuring your waist measurement minus 5"
3. you are going to want to cut strips of tulle that are two different lengths. So for example, your longest length would be four more inches than the shortest.
4. then you want to tie the strips of tulle in slipknots on the elastic, with all the long tulle strips going one way and all the short tulle strips facing the other.
5. when you are finished you can turn the tutu "inside out" and the tulle will be a short pouf-y layer on top and a longer layer on the bottom. It will be nice and full, but you will probably still need bloomers of some sort of cover up underneath it.
If this does not make sense, please post. I'll try to clarify if need be.
