How did you go about constructing these? I have been trying to make one for months now and can never get it quite right.
I measured the basket's internal dimensions and then added appropriate seam allowances. I usually use 1/4 inch for sides and bottom and then a 1/2 inch for the top.
All the sides were trapazoids since the bottom of the basket was more narrow than the top.
Then I sort of pretended I was making a bag but without the handles.
When I finished the exterior and then the interior, I placed them inside each other and put the entire thing in the basket. I then marked where each strap or tie should go and pinned in place.
Sewed it up and off I went!
The key for me was double and triple checking measurements....otherwise I end up with something too small, too big or just skewed in general.
