patchwork comforter/throw for a first tiemr

[bruffin]

We are doing DD's bedroom up and I want to make her a fairly simple patchwork throw for her bed with her favorite band on.

I have found some cotton material that can be put through an ordinary printer so can make some squares with photos of the band on and their logo.
I want it fairly simple, just squares and no complicated patterns, although it needs to be double sided so that when she no longer like said band she can just turn it over.

Not sure where to start and what is a Jelly Roll?
I assume I need padding, does this get sewn at the same time as I am sew the squares together.

Hope I'm not too late to help you.
A jelly roll is a set of 40 srips of fabric, each about 45in long and 2.5 inces wide. They come in coordinated rolls to save you having to get small amounts of lots of different fabrics. Also good if you are pants at colour planning.
A quilt usually has three layers, like a sandwich. The top which will be the layer with your printed squares. I wouls suggest you alternate these with other fabric squares in a colour to co-ordinate with the room - perhaps something simple with a tone on tone pattern, or even simple calico which is cheap. The middle layer is your sandwich filling or wadding - polyester is cheap but cotton is nicer (but can shrink so wash first). The bottom layer is usually plain and is often made of something cheap and ghastly which you bought when hormonal- because it won't show! You may neet to rethink this layer for your project.
The way to do it is make your top layer, then get your wadding and backing and assemble them on a large table or the floor - the thing is to get everything really flat and wrinkle free. Then you pin or tack the layers together really well before quilting it by hand or machine. It is a lot of work.
Please ask again if you need more help.

Thank You

I have the cotton printing material so I am going to see how that goes first.

Then we are going in search of materials, would like to have started before christmas but can't see it at the moment.
