I backed the sewn circle with navy coloured foam, and then made a ribbon rosette by sewing a running stitch down one side of the ribbon and pulling it so it gathered.
On the inside I reverted back to papercraft. Nice, safe, quicker papercraft. I used contrasting gingham blue papers to provide a 'baby boy' background and make a frame for my message and the pram embellishment.
The message was written on vellum with a black sakura glaze pen (which gives a very slight 3D effect) so the backing paper can still be seen through the translucent paper the message is written on. I decorated the frame with some brads in the corners and then raised it by placing foam at each of the four corners.
I made two embellishments for the inside of the card - a baby's bottle and a pram. This was mostly cut out paper shapes, and then being backed on blue foam, although I created small, silver wire circles for the pram's wheels too. They were secured either with doubled sided sticky tape, or more foam pads.
* Also, note my total idiocy of sewing four balloons that were later hidden by the sewn circle. Idiocy.
