>Can anyone please answer some basic ballet slipper questions for me -- I am rather clueless:>1) What's the best way to sew on double (crossed) elastics on a canvas slipper?>2) I have been told to tuck the drawstring ends under, but am I supposed to tighten and knot them in a permanent matter (they are rather long when I tighten them) and can I cut off some of the excess length?>Thanks in advance![/i]
