Interfacing question
 

I’m sewing a oval fabric carrier bed for a doll. Next step is attach the bottom to the sides. Sides have double layer of fusible polyester interfacing & it seems fine but pattern says use the same for the bottom. I think something more rigid is better. Making a JoAnn’s trip in a couple of hours when store should be less crowded. Recommendations for bottom interfacing ?

By the way, when I get this carrier done, I make a 2nd one because the doll came in a boxed set of twins ! Good thing I can sew, the same carrier is selling for &49 apiece !

I think Deco Craft will be sturdier. I use it for placemats for a flat look and it's sturdy. Comes on a bolt by Pellon.
