Backdrop suggestions

Greeting to all.
I'm about to purchase a new backdrop or two,.for my on the go studio.
Muslin...for portrait stuff.
I;ve heard for years how good Denny's Masters are..
Any others that you would suggest I look at?

I like the durability of the muslin, and the look and feel.

Thanks in advance for yur replies.

Cheers, Ken

I used muslin for quite a while but found I spent way too much time fixing wrinkles and spots on the B/G....I have gone to seamless and will never go back! If you are looking for patterns and such then you will have to spend the money to get what you want. I shoot plain colors and add gels to get any additional colors I may want.
