I was asked to make these and I didn't have a huge amount of time so they had to be quite simple. I have used this layout before which I pinced from Michelle (cardgrotto).
Just embossed white card with happy birthday folder and mounted onto pink card. Mounted some plain white card onto pink card and added the 21, which is Sizzix lollipop alphabet, which I cut out in chipboard and added pink to the top of it. I went around the edge with stickles. The bottle is a die cut I have which I layered up and added some peel off numbers for the year that she was born.
