Yes, white is easier to see the seam through than darkroom colors . Very often you can press away from the white, but if you can't, make sure that there is not also a bit of dark fabric showing behind the white. What I mean is if the white is joined to a dark, and you have to press the seam toward the white, sometimes if your seams are not matching absolutely dead-on, you'll see a sliver of darker fabric sticking out behind the white seam, and that will REALLY show if you don't trim it off a bit.

WOWs seems to do that more than others.
If you can, press away from the white, though I know that's not always possible.

Keep in mind that you will have the white batting in behind that may help minimize what you are seeing right now. Try laying your block on some batting to see if that helps.[/QUOTE]
I agree. Hi and welcome to the QB!

White simply is a more transparent color just the nature of the beast. You must remember when quilting it to use a white batting, anything else will shadow through.

Hello and welcome from the UK. I bought some cream fabric last week on line that was very thin and flimsly. Even after washing this showed the under seams badly. I asked advice on the board about Kona and Bella solids and then bought some Kona natural and following advice from the ladies here, washed it. The Kona fabric was a better quality to start with and washing seemed to make it a little 'denser'. I'm certainly much happier with this than the fabric I originally bought.

Washing vs non-washing. Now there is a good topic. All I can tell you, as a new quilter, one teacher washes always, the other never washes as she likes the look of a quilt after its wash, looks older? Anyway, if you wash your material, make sure to treat it with starch before cutting. As I have washed and ended up with a screwed up block. Then did it again, after being told to starch "well" before cutting, and it came out acurate.
