If you have chosen the flat-lining option you are ready to attach the brim to the hat sides.
Apply contact glue to the tabs and to the lower inside edge of the sides. Wait a minimum of 5 minutes, you may find if the fabric has soaked all the glue up it’s a good idea to apply a second layer of contact glue to both tabs and inside the lower edge of the sides. This is important because you want this join to be strong and firm.
After you have applied the second glue layer you need to wait for around 5 mins. The glue should not be gooey but almost feel dry, with a slight tackiness.
Note contact adhesive is not adjustable, so mark your hat centre front points and centre back, on the brim and the sides with tailor’s chalk or a visible textile pen, or use a pin. Using these marks align the centre front tab first.
Press to the inside of the hat so the brim is firmly pushed up to meet the hat sides. Repeat for the centre back tab. Then repeat at the side quarter mark, then the tabs in between.
The pattern is made to fit exactly, if yours does not fit then it has not been cut exactly to size or your covering fabric is too thick.
