We use those gowns all the time. The parents so appreciate them. It is difficult enough to have to go through that experience and loss and there are few things we can say or do to help support them, but this is one of them. I also use fabric ink and take the footprints and put them into an embroidered project that has their name, date of birth, time, length, weight, and if they were born alive, the date of death. There are times when it just isn't possible to get footprints, so I create something with a stamp of a footprint. One time, a family had 15 of their family members there to support the couple. I was unable to get footprints, so I did all their handprints and made a wall hanging with the family member's names' embroidered on the handprints and put the baby's info at the top after embroidering, "With these hands we will lift each other up while we mourn...and the baby's name."
I always ask their nursery colors are or whether hearts or butterflies mean more to them, colors, Bible verses, etc. I try to design it with their input, so each one is different. I only had pix of two handy that I had covered up the names for their privacy to share.
I learned PSP to create T-shirts and art for our biz. For those of you who use it for scrapbooking, doing layouts of their babies would be a huge gift. It is the only pix they will ever have of their child.
Art is therapy - for those of us who do it and those who receive it.
