I have open shelves in my office and all my bias & twill tapes are stored in a cupboard box. Yes, eco-friendly as I recycle my boxes but unslightly!
As part of mystudy makeoverI am covering a few wire baskets I found in the garage with fabric. So I didn't have to line them, I used gingham (no right/wrong side) and added bias to the exposed seams.
I haven't given you any measurements as all baskets will vary in size.
Take your wire basket and measure all four sides of each side plus the bottom.
Add a margin of about 1 - 1.5cm for seam allowance.
You need to add an additional 10cm for the overflap to each of the four sides top - the widest part.
Sew all your sides together. Then add the bottom panel.
Check that it fits nicely into your basket.
Trim back all your seams ready for bias.
Because I am not adding a lining, I have added bias binding to cover the exposed seams. They will be on the outside of the basket liner.
Start with all the side seams first and then bind around the bottom.
Add bias the whole way around the basket liners top edge.
I have added an elastic gingham trim (from Spotlight) which will gather the top edge and make it sit firmly. Stretch out the trim as you sew to make it gather. You could add thin elastic to the under side or even do a couple rows of shirring to give it the same gathered effect.
