Find an interesting t-shirt and a contrasting/matching coloured t-shirt.

(For instance a white t-shirt with logo and a contrasting orange t-shirt)

Cut 4 squares from white t-shirt. Pin the 4 squares onto contrasting t-shirt and cut out.

I cut 4 squares but you could do as many as you want.

Pair up the white and orange squares.
'good sides' facing outwards.

I turned the edges in roughly an inch and pinned. This is so the edges are neat.

You could always not turn edges in and just zig-zag stitch around edges to finish off.

To created the 'quilted' look I sewed in graduating squares; getting smaller the further centred they are and finished with an X sewed in middle.

You could 'quilt' and sort of pattern, for example;
* Diagonal lines
* Continuous line spiralling inwards

* Lots of small 'X's

Continue on and repeat above steps to finish all coasters.

Then Stack on top of each other and top with bow and possible tag- detailing the 'ingredients' in your item!

Good luck!
