First time posting a pic so fingers crossed. I saw cute anarchy's pic in the other thread but was unable to locate the original thread. You would not believe how many results you get searching for box and basket.
Whilst waiting impatiently for her lovely response to my query, I came across Diyosas tutorial for upholstered boxes. By combining your pic and her tute, I made something similar.
I wasn't sure of the measurement so I used a Fat Quarter, squared it up and made rouleau tubes out of the scraps. No wastage! I used scraps of quilt wadding to encase the cardboard on both sides, as Diyosa did.
I love this and plan to make more as soon as I have some more scraps. I have been on a box/pincushion making binge to use them up and have been too successful.
