if as you say, you are a "bit cack handed" then a very simple folded rose might be your best option??
on the fold - cut a very long slim oval - as deep as the height you want your flowers to be( + seam allowance) - & aprox 5 times that in length (with heavier cloth, such as lycra, 4X)
Make a running gather stitch along the cut edge, taking up both layers of cloth - leave a length of thread hanging to pull & gather
optional - stitch seed or bugle beads along the folded edge, again a running stitch is fine, but don't gather this 1
go back to cut edge,- pull thread to gather up & "roll" into a flower shape, secure at bottom end, & "fluff" out the petals - you should now have a rose with a beaded edge to the petals
hope that helps
