b - ozdoba ze slomki - ...............
so called pająk
, a kind of folk chandalier or hanging decoration. Wiki says its specific for all polish regions but I've always recognised it as central Poland folklor item.
c - malowane kwiaty - Mazury area?
no. These are wycinanki (a paper cutted in patterns)
łowickie are the most famouse I guess but they are popular in many regions.
d - czerwone korale - krakowianki!
not góralki? Maybe you're right... ;)
PS - please, fill in blank... :)
