Hi everyone,

I'm new to tthis forum and new to quilting - I've made a couple of quilts after watching Jenny's tutorials and they have gone OK.

Now I am looking to make a version of the Tranquil Triangles quilt but was planing on using quarter square triangles made from a layer cake to make up the nine patch. Do you think that it'll work ok? and if i make it 4 blocks wide x 4 blocks deep how do I know how much fabric to buy for the backng - and for the binding, the maths is really hurting my head
