Hi
just thought I would let you know what visaflex is Hope I have spelt it correctly ,comes from the US
it is paper with a film or web mat (type of glue) on the back.when ironed to fabric it sticks,simple as that
what you do is trace your designs in reverse on to the paper side,over a light box ,window or what ever you use.
cut each design piece out with a scant 1/8th of an inch around it.then iron to the back of your material that is to be used in the design
I then place my design pattern sheet correct side up on the light box,with a piece of baking paper.over the design,then i cut out my pieces and peel off the paper and place it on the baking paper to where i have cut these pattern pieces for,the heat of the light box lets them adhere a little when completely satisfied with my applique i gently lift the baking paper off and take to the ironing board placing a piece of baking paper over the applique piece mainly to protect the iron from any glue fragments
your applique piece is complete now when ready peel design from your baking paper and place on whatever you are making,then you sew around each piece by hand or machine
I use this method all the time I do a lot of baby bibs and do t-shirts etc for my grandies and I made their quilts this way,as you can use such tiny pieces of fabric hence the panic of getting pieces to sit right.for turn under i think your freezer paper might be better .hope this has been of some help for you to understand what visaflex is used for
cheers
