It is wonderful.
As a mother I totally love anything that my children take the time to make for me.
Our daughter gave DH a ceramic scenic piece (train on a track) which she made in school (she is 9) and he was totally over the moon... he will treasure it forever.
Hand made items have a value greater than money as the hold all the love that went into them!
I am so sorry that your father did not see the love that comes from your gift, he in the one with a problem... certainly not you! If it were me, I would treasure it.
Hugs
