Hahaha no worries. I've actually cut some common refractors to see what the result would be. When the pieces are placed next to each other, the rainbow effect is not continuous, and it looks like a shattered mess!:)
Several vintage pieces will be finished soon - but here's a couple of modern cards I recently completed:
1993 Finest Ken Griffey, Jr:
1987 Topps Kirby Puckett:
3 to go for my complete 2006-present run! Only looking for the base autographs of the following (no red ink 10's, no black frame/25's, no Ginter X):
2010:
Anthony Gatto
2016:
Michael Phelps
2017:
Sarah Michelle Gellar
