I love this cute image - it could be used for a baby's 1st birthday card too.

For this one print:-

From the blue baby paper pad

The I Love Mummy reverse background onto quality white paper
The Baby Boats blue background onto quality white paper
The free mini envelopes sheet (the free bonus when purchasing all 3 paper pads) onto quality white paper

From the Baby Antics set

The Baby Boy with Balloon motifs onto quality white card
The Baby Bottles sheet onto quality white paper
The blue baby miniatures sheet onto quality white paper

To make the card, take a white 7" x 5" card blank and add a 13 x 12.5cm piece of the I Love Mummy background and a 5 x 12.5cm piece of the blue baby boats background with double-sided tape.  Butt them up neatly together as no border strip was used on this one (which are always useful for covering up messy joins!).

Stick one of the 11cm tall motifs and a greeting onto larger pieces of silver metallic card with double-sided tape, then trim round with a craft knife and ruler to leave a small border around each.  Stick them to the card with sticky pads.

To make the baby bottle, cut out both the white and blue parts separately from the baby bottles sheet.  For the white part, wind the paper tightly around a cocktail stick so that you finish with the marker-line end.  Stick into place with double-sided tape, glue stick or a small amount of tacky glue.  

Make the top (blue part) of the bottle in the same way but this time either graduate the paper as you roll it to form the teat of the bottle or roll it straight and push out the paper at the end to form the teat (or a bit of both!).  Once you're satisfied with it, ease in a dollop of a strong tacky glue such as Aleene's to keep it all in place.  Stick this part to the bottle part with further tacky glue.

To make the envelope and invitation, cut out both from the sheets using a craft knife and ruler.  Make up the envelope and stick it together with your chosen glue.  Tuck the invitation into the envelope and stick both items together to a scrap piece of card with double-sided tape - this just raises them up a little and creates a little shadow which makes them show up better.

Add the baby bottle with tacky glue.
