What are you most proud of? Finally got it done after many missteps! Will make another soon so as to not forget what I have learned!! What advice would you give someone starting this project? Make sure all stressed seams are sturdy. Example:top edge of both front pockets, side seams especially where neck strap is connected. Patience as you are working with smaller pieces. This carrier is unique to his 4s. My 5 will not fit it as it is wider....not that I would use it!!
