How much fondant do I need to cover the Wilton's number 1 and number 2 cakes? I thought I had 2kg but i only have 1 is it going to be enough?

I'm not sure how big those pans are, but I would guess that 1kg won't be enough.

One kg wont be enough for both. Minimum 2kgs if not 2.5kg. they are approximately 12 3/4 x 8 1/2" x2 in dimensions. Better have on hand 2.5kg

Here's a great chart for another brand of fondant that shows amounts needed by tier size. You can download it as well as a color mixing guide here: http://r20.rs6.net/tn.jsp?e=001v4bAZTMLgkt3HuzM31qMPGqXMqI6k-99SWSD3LfB-vQBg10H3DnA-FBtDjwP2ZwI9cuxutie1guRQ7nrtQZCRPWYwLgqtPQJiwNG1rc6JLrYqm2nHl0ekQdCc7h9vT_Y23hnhn9Hwc8eh9lGzrUsFZc-yEK-XU8nltXrzuiEXNhDNfVDQSKNcAmMLQiysH2yKRZKxvDGES0t4kjIjvRnyDaBkMW_u9W37_3BC1tZfIf8ceoLMmb5s7_dXi6zSQbS_BjaoKdrprzk63iYxp6hAlpJcYrOMRTv-ujQ71W6U0VPuwnJiuqfmtGxYMESj-DpOZJP0EIq6NRO0aETajPqT2rhxFdnAwvlJi5vFoGrjN-B1sKvD0-_W0KPWwn_58Si_JWZ2DDX8=

Please be sure to note that the guide is for covering only and not for any other decorations you might be adding. Best to have too much than not enough.
