I recentlu purchased this mold and I'm hoping someone can help me out and tell me what would be ideal to fill this with? I'm brand new to molds with this many sides and Im clueless. I usually fill molds with fondant but it seems impossible here. Thank you in advance 

Following this because I'm  having the same dilemma only with the lacey silicone molds. Its says fondant but then how do u get out the fodant out from in between thr crevices? Plus it loses its shape whennu pull it out.

A pic of  your mold would help, but by the sound of it what you need is a product like Claire Bowman's Lace mix

The right product for the very fine lace molds. Like many you will find on our website www.fondantmolds.com.au

Good luck
