I also ordered padded flat rate envelopes on line last week. I have 2 in hand so if they are late, no problem. I will be sending a dark blue print to my group. I hope you don't mind Jaba, I stole your idea.
It is a good idea to send the background with your F8 with your fabric that you want your block to be made with. That sentence looks wrong, oh well. I don't know if I will send my own background or not. The last boom I was in, I requested white or white on white and didn't have a problem. Only one returned a different background and that was so lovely that I certainly couldn't complain. I plan to build it up and use it for a pillow.
