1 sheet of felt (or more if you're doing different colors)
Felt glue and/or hot glue
Card stock in coordinating colors
We'll start with the orange loopy flower.
Fold one edge of felt over lengthwise. Cut out this piece, but don't cut along the fold.
Using felt glue or hot glue, glue the unfolded edge to itself.
Make evenly-speced cuts all along the length of the felt, through the fold but not all the way to the glued edge.
Cut out a circle of felt or card stock. Put your choice of adhesive all over the circle. Starting with one edge of felt, lay it down along the edge of the circle, following the edge of the circle. When you have gone all the way around, continue winding toward the middle and sticking it down.
Using another piece of card stock, apply adhesive to the entire surface (here I used adhesive tape on a shape I cut out with a puncher, but you can use whatever you like).
Press that into the middle of the flower and ta-daaa!
For the black flower, it's the same procedure, except I cut down the fold after gluing the edges together, and I made the cuts more closely spaced.
"Fluff up" the petals, and you're done....
