You'd probably be better getting a strap. You'll find it makes the guitar more stable, even if playing sitting down.

I do use a strap it still slips off my thigh..can strap be to long or to short?

It needs to be adjusted to hold the guitar in a position that feels right, so yes, it can be too long or short.

If you want to use one of these it will solve your problem. I have the Hercules. Although designed for use with Classical guitar, they'll do the same job with any guitar. So will one of these if [u]adjusted properly[/u]. Try that first. Although IDK why it should slip off your thigh in the first place even unrestrained other than by your natural balance?[br][br]Now if you said that happened with body heavy and awkward shaped Les Paul, I could completely understand, but the Strat body curves/shape is ergonomically suited to being played that way.

GL. One of those three solutions will work.
