I'm so sorry the photos I attached are so large, I can't re-size unless I e-mail them.
I wanted to make a fabric box to hold chalk for my grand-daughters. I made each of them place-mats which used chalk fabric to keep them busy at the holiday table.
I had cream cheese boxes which were close in size that I used for the pattern.
To adjust box size, open up the box by pulling it apart, flattened it and draw 2 pencil lines down the box about 1 inch apart ( any amount you wanted to decrease the size of the box).
Cut the box apart along one line and used blue painters tape to overlap the pieces along the second pencil line.
Trace the box outline onto the paper side of Heat an Bond Heavy. Using a paper scissors, cut out about 1/4” away from the pattern. Make a second copy of Heat and Bond Heavy.
Fuse the 2 pattern pieces of Heat and Bond Heavy to the wrong side of fabric.
Center the cardboard box on top of one fused fabric pattern, cover with parchment paper and fuse on both sides of fabric.
Using fabric scissors, remove unfused fabric. Trim close to fused cardboard, but leave 1/8” to 1/16” edge of fused fabric around box.
Place fused sides together (right sides of fabric to outside) and fuse again using parchment paper to protect ironing surface and as pressing cloth between iron and fabric.
Trim. Crease along original fold lines of box.
Glue tabs, clamp. I used Elmer’s wood glue because I can borrow it from my husband’s shop and it is a strong hold and gets tacky quickly, but other types will work.
