If the guest did something with their own hands, then he gave it a lot of time and prepared for the name of the friend in advance. At first I determined what interests the birthday person most. And then he did his best to prepare a surprise for himself. It can be a homemade card with sincere wishes, a hand-made souvenir, a frame for your favorite shared photo. To such a thing a friend will treat with special respect and accuracy.
A gift made by one's own hands is not only intended for your friend, but it also carries the warmth of the donor's heart. After all, the one who made the gift, put a piece of his soul into it. Looking at your craft, the birthday boy will smile and think about you and your strong friendship.
I very much hope that my grandfather managed to convince the granddaughter that it is better to give something done by oneself than to buy a soulless thing in the store.
