And obviously, for such frail parts, plan your cutting order, postponing the removal of paper which reduces structural strength, thus lessening the risk of accidental deformation. This usually involves:
- leaving a generous white margin around each part
- start cutting from the inside (the spindly "petals" on the rightmost parts should be cut last)
Also, I'd try not completely removing each white "window" one at a time, but leaving uncut paper in place as long as possible. For instance, doing all or most radial cuts first, and only then the round cuts - or vice versa.
