Love the colors you chose and I am sure your little niece will love laying on this soft quilt.
This is cute! what are the dimensions? Did you back it with minky (or is it minkee?)? It almost looks like the top is pieced with flannel? Your sister is going to want a bigger one for her!
The size is ca 100 cm * 100 cm / 3.37" * 3.37"
The fabrics are cotton except a few pieces which are made from a hand towel (liked the colors!). To add some texture for the baby.
It's filled with cotton quilt stuff (sorry, my English fabric terms are under construction ). No synthetics because that's dangerous for a baby.
I stitched through al layers at the end to add a bit of height.
