ASLPro.com uses "7-Weeks", and David uses "8-weeks". I am not sure why they don't use the same sign. It seems like it should be for the seven weeks, so I am not sure why David makes it 8-weeks. Maybe you can email him directly for his wisdom or any other questions you have:Rachel0 said:Thanks for help, I got same info too, but SEVEN weeks, not EIGHT weeks. I will check aslpro.com. THANKS FOR ALL HELP!
