Thank you! My boys who are now in their 40's played with Legos and now my grandson who is only 4 loves to come to grandmas to play for hours with grandma making all kinds or stuff. I still have a few of the old instructions but now with your website, I can continue to create more. 
Thanks again, Sandy
