Irish baby bonnet made of Irish linen and edged with a half inch of lace is known as the magic hanky bonnet.  It is an ideal gift for a baptism, that can later be used for a wedding day keepsake hanky!
 
The Irish Magic Hanky Bonnet includes the following poem:
I’m a little hanky As beautiful as can be, And with a stitch or two a bonnet has been made out of me. I can be worn home from the hospital or on christening day, And then I will be tucked away to await the wedding day. On her Wedding Day, a hanky I will be, For every bride needs something old and surely I will be. And if so happens to be a boy, and someday he should marry, He can give his lovely bride a hanky she can carry.
