OK blogettes, i know i am techno challenged so no video tutorials from me, bu i am hoping that these pictures may help.
First of all let me just tell you that you will find it very difficult to punch out some vellum with a normal craft punch so before i went ahead and showed you how i did mine i tried all different grams of vellum and with these pictures i have used a normal stationary trace paper that i colored with adirondack, i think that the normal trace paper is only around 60gsm. so it is tissue thin.
2) Lightly press with your tool onto each petal making it slighty curve, and once you have done each petal, moving in circular movements, mould the centre until all the petals start to fold in towards the centre.
3) Now depending on how well they are curled or not, doesnt really matter since you can flatten it or curl it more as you see fit when glueing them together. However i might just add for you not to start with the samllest centre piece but rather with the flattest piece first and then work your way towards the smallest bud in the centre.
If you gonna leave some feedback please be kind, he he
