Determine your fabric, iron-on, and design that you'll be using.
Open DIY dice design in Cricut Design Space and unhide squares you'll need to cut fabric. Finalize design and select Make It.
Place fabric right side down onto FabricGrip mat and load into Cricut Maker. Follow on-screen prompts to cut fabric squares in all fabrics you're using.
Place iron-on vinyl shiny side down onto the StandardGrip mat and load into Cricut Maker. Mirror image then follow on-screen prompts to cut fabric squares in all iron-on vinyl colors you're using.
If necessary, use weeder to remove any excess vinyl backing from design.
Use Cricut EasyPress to iron vinyl onto fabric squares. Remove backing once cooled. Repeat with all squares.
Sew blocks into a cross with one extra block on one of the sides, right sides sewn to right sides.
Fold the cross diagonal and sew two sides (see images in post for details) together.
Unfold the cross, fold diagonally the other direction, and sewing the remaining sides together.
Sew two of the three remaining sides of the dice top to the sides of the dice so you have one remaining open flap.
Carefully reach in and pull the fabric inside out so that the right side of the fabric is now on the outside.
Stuff the dice with batting.
Hand sew the top shut using either a ladder or whipstitch.
Notes
Make sure to toggle the mirror tab to on before you cut your design. Your iron-on needs to be cut mirrored so that it shows up correctly when you iron it onto the fabric.As you are sewing this part, make sure to arrange your blocks in a way that all of the sides will be facing the same direction and so that your various fabrics are separated from one another.One thing to always keep in mind is that right sides are ALWAYS sewn together with right sides. And when I say right sides, I mean the front side of the fabric, or the fabric you want showing on the outside of the DIY dice.
