Here are recipes for making your own Modge Podge Glue. Cheaper than buying, has the same results.
Modge Podge Glaze
Mix 3 parts white glue (elmer's or any cheap brand) to 1 part water.
Add more or less water to get the desired texture and thickness.
Add 2 Tbsp. varnish, for shine. Put into container with screw on lid.
Just Like Modge Podge
1/4 c. sugar
1/4 c. non-self rising flour
1/2 tsp. powdered alum
1 3/4 c. water
1/4 tsp. oil of cinnamon
In medium size pan, mix together sugar, flour and alum.
Gradually add 1 cup water, stirring vigourously to break up lumps.
Boil until clear and smooth, stirring constantly. Remove from heat.
Add remaining water and oil. Stir until thoroughly mixed. Put into container with screw on lid.
also, i'm loving this blog, it has tutorials for turning a maternity shirt into a non-maternity shirt (and i have a few that i love and need to try this with!) and how to's for cute girl clothes.
