This magnetic opening A4 frame is all ready to use as your positioner. Tape the strut on the back of the frame to the base to prevent it from opening, peel off the protective layer on the acrylic front and voila! You are ready to go! I upgraded mine by taking off the 4 plastic tabs inside, doubling them up and re-attaching them to the inside of the front frame to make opening easier. An A4 magnetic sheet taped inside provides a base on which to use a couple of neodymium magnets to hold down your project. I happened to have a few overhead projector sheets, so I printed a grid on them, one for the base and the other for the top to provide guidelines to position my stamps. You could always use a thicker A4 acrylic sheet in place of the thin one provided if you wish but the original works just fine. You can also make a mini positioner using a CD case and some 'fun foam' as a base. Simply take off the tabs and cut away the end of the base to provide a flat surface. This home-make is very handy for using with sentiments and small stamps.
But one thing I do: Forgetting what is behind and straining toward what is ahead, 14 I press on toward the goal to win the prize for which God has called me heavenward in Christ Jesus.
May you be richly blessed this year and come to faith in Christ Jesus who died for your sins so that you may be at peace with God.
