The answer is
Silver Tinsel
Because
treating <Ψ| as "BRA" and |Ψ> as "KET" (their names from Dirac notation, as they form the begining and ending "BRAcKET")
We get
coBRA basKET
BRAclet trinKET
celeBRAtion rocKET
viBRAnt marKET
BRAin locKET
zeBRA sKETch
Taking the
letters from the numbered blanks from the pictures
Gives
the Christmassy SILVER TINSEL
