It tells me to glue all outside window sills (short sticks with corner notches at both ends) into their respective window openings. But it doesn't refer to what sheet to go get these short sticks, etc. The instructions are overall extremely vague and I am struggling to understand any of it in a meaningful way. I desperately need help with building this house....please!!!! I've had this house for 2-years and struggle to make success on my own or find anyone that is able to help. I've put it to the side for extended periods after losing hope. I want my granddaughter, and my son's niece, to love this house!
