Looking for advice on how to achieve this webbing or mummy texture look? I’m assuming strips of fondant? Anyone ever done anything similar to this before? Any tips or advice would be appreciated! Thank you!

I cannot tell from the picture if this is fondant (an extruder would be handy) or piped frosting.  It could be created either way.

1st I want to welcome you to our forum:)   Being that this your 1st post you will not be able to reply to any post for about 30 days so if you have anything to say just start a new post referring to the one you are talking about 

I am almost sure it is piped lines.  Tip # 3 w/mild squeezing while turning the turntable.   Add extra lines w/tip somewhat away from the cake:)    You could try/practice  both ways on paper  to see which you like best
