A few weeks ago my son came home from school with a request to dress up for a Titanic themed day at school. We quickly realised we had very little that was era appropriate for him to wear and it occured to me that the easiest thing to make would be a life jacket.
I did some googling and found this example of a bouyancy aid for the ship and I used this as my inspiration.
What follows is the instructions for a very loose replica. The instructions are detailed, but the process is very quick so do not be put off! Our version was very successful, so much so that he ended up being appointed as Captain of the ship on the day.
