You can buy blank cards and envelopes, kids can wire and decorate them but much nicer than using a regular A4.
I never buy individual cards anymore for parties, we get a massive box with a selection online at the fraction of the price and the cards are lovely.
For parties, I never give any tat, only presents I’d want to receive. With some efforts you can get amazing stuff when offers. I buy whenever I see something nice in offer and out if in my party gift pile.
Never any stress or waste of time on a Saturday shopping for a party gift.
£5 idea is good, one mum used to do this, HOWEVER, I just couldn’t bring myself to ask for money ... it feels so rude.
Also, many children love opening gifts.
Mine never really get spoilt like that so realistically it’s only ever Christmas and birthdays they have this.
Twice a year is not that bad.
It’s also only a relatively short period they have massive parties. When older it’s smaller parties.
