start with something simple first. something like a "box" pattern. Chose your material and then cut it into squares (I'd suggest 6" - you can get templates from spotlight which makes it super easy). Arrange in a pattern (my first one pretty basic, two materials alternating). Once they were sewn together (I pinned them together and sewed in lines then joined the lines), I cut a "back" (I chose one colour and it was slightly bigger than the sewn piece. This mean I could "fold" it over and have a it of edging). I put batting inbetween the two large pieces of material and sewed around the edges.

HTH and makes sense!
