First read the general instructions.
Once you are sure you understand the basics, download the birthday cake SVG File. The instruction sheet in the download file explains how to upload it to Design Space.
Cut the outline from black cardstock.
Stick the outline to the contact paper and re-cover it with the protective backing paper.
Cut out the various pieces from paper scraps in your scrap bin. Watch my video about cutting multiple colors on one mat.
Use yellow for the flames and try to make the two tone layers similar colors. Try to make the layers at the top different colors.
Start placing the various pieces on the cake with the tweezers.
DO NOT TOUCH THE STICKY SHEET WITH YOUR FINGERS
Do not try to fill the stripes on the candles. I tried and it will make you crazy (and we are all already crazy enough). You can color them with marker if you want but just leaving them white is fine too.
When all the open spaces are filled, check to make sure all the paper is secure. Press the protective sheet over everything and press sorta hard. Anything that seems loose, glue down with the liquid glue and let dry for at least 30 minutes.
With scissors cut around the outside leaving as much of the outside black line as you can.
Use the piece as you like. I took the cake and the present bear and made a birthday scrapbook page.
