Help Needed

Well ladies... I'm pregnant!  It only took three IVFs, one FET, and countless injections over the last four years.  It still hasn't sunk in yet.  I keep waiting on the bottom to fall out and the test to be false.  I'm having an ultrasound in a couple weeks to do a head count.  I had two embryos put back so unless one split I could be having twins.

I know these colors are off, but heaven help me I couldn't get the camera to take a picture with the color right on.  With the "I love Mommy/Daddy", green stripe, and yellow checkered I'm going to make receiving blankets out of them.  I want to make a blanket out of the minky celedon fabric I'm making it a blanket.  My question for all of you is, how would you finish the edge?  Satin binding?  If so which color, white?  They don't sell it the same color as the fabric.  I thought about making bias tape, but then nixed the idea.  I've seen several blankets recently where they fold under the edges and sew them down.  Should I do that?  How would you finish it?

Here's the blanket I've been crocheting.  I did switch patterns from what I previously posted.  I went with Baby Baubles Baby Blanket.  The duck onesie is what I took to my egg collection.  I told the head nurse I just needed something to fill it.

So ladies, how would you finish the blanket?
