i agree with Summer - headed to the cutting table to figure it out
sure enough - to frame the 10" layer cake you will need 2 10" strips and 2 14" strips (48") ...... since most jroll strips are wof 42" - 44" - you would need 2 matching jroll strips for one block and end up with a length that is to short to create a second block by just a few inches........ certainly can be used for borders though!

.
SO to figure out how i could use one layer cake 10 x 10 square and 1 jelly roll strip wof for each block - i cut the layer cake down to 8.5" square and cut 2 8.5" and 2 12.5" strips from the jelly roll strip (42") ........ and wahla !!! here are the resulting magic squares

YAY!! ..... the scrap 1.5" strip cut from the layer cake i set aside and will sew together end to end to make my binding strips! This should be fun!!
Thank you Jenny for your awesome new tutorial .... Luv Ya!!
