I've given away a few but either those people don't wash their quilts or nothing awful happened, because I've never had any bad feedback. But now that I'm selling quilts, I'm worried about disappointed customers!
So last night, I took the plunge and just added the navy floating coins baby quilt to my regular laundry (a mix of hot/warm water, liquid detergent, regular setting as I don't have a gentle cycle setting).
I took a photo before, just in case it came out mini ;) I also measured it: 26" x 37.5"

After the wash, it came out in one piece and feeling softer. So far so good. I measured it again: 26 " x 37.5" - great!

Then I thought, hmm, I'm in a country where people throw everything in the dryer... so in it went, again, no gentle cycle and I used the hot air instead of cold.
Well.
And again: well.
Now I've heard people RAVE about the crinkly look, which they get by not pre-washing and the quilt shrinking a bit. I got that. Very crinkly, not sure if it's my thing.
The shrinkage is definitely not my thing.
The quilt now measures 25" x 35". It lost 2.5" in length! Aaaaaah! I'm NOT happy about that! Is this shrinkage relative? Will a queen size quilt shrink 10" in length?
I'm going to wash one more quilt on hot then hang it to dry, and after that, there'll be some advice to my customers and other quilt recipients!
It looks so tiny now...

On the bright side the coins are nice and fluffy :)
