Just got a necklace made by Smallprints and love it (and PS this is not an advert, I was just impressed). I had mine done at a fair in DB and can be difficult getting little ones to comply with having the print done. If you google them you will find the website.
I had things made twice by Smallprints (necklaces and key chains). I'm very happy with their service, they come to your house when its convenient for your and your little one.
About a year ago, I hosted a party with My Happy Sunflower and ordered a really cool necklace for my mother--the necklace had my son's handprints and his name in Chinese. At the time my son was 2-years-old and the owner who came and took his handprints was very natural with him--she is also a mother of two small children, I think. I was pleased with the final product. I really can't remember how much I paid for the necklace but they did a great job and also came to my house. I just noticed they have a shop now in Wan Chai and have also started offering pottery classes. Also, not advertising for them but we did have a good experience with this company.
