Hi there mateoh, welcome to the Board. You'll have noticed there are some members who post a lot, other's who are rarely heard from. There is not only lots of good information to be heard here, there are also refences to many other places to go for help or just to look at something different.
In a way we are all newbies. There is always either something new or something old that has been changed. Or, like me, may have been a "quilter" for a long time but have actually finished very few pieces, just collected a large "stash" - to me that means more than you can possible use if you live to at least 100.
Have fun with it, enjoy the different personalities and opinions you see and let us see what you make. No one will criticize unless you ask for a critique; even they most are gentle. Joyce in Delaware
