I have only recently seriously started to wear nappies after a number of false starts. So for what it is worth, I lie down in changing position,legs bent, and start with the leg tabs, angling them slightly upward and as tight as possible. Then the waist tabs, this time slightly downwards. I have tried the standing with wall method but laying down works better for me. The big two tab nappies are in my opinion more tricky to get right. Legs ok but waist a bit loose. Hope this helps, feel a bit too inexperienced to give much more advice.
