Cushion: Best of Both Whirls
There are no curves here. The spirals you see are made entirely from straight lines. You can make Best of Both Whirls from 1 large module or 4 small ones. Either way will give you exactly the same size so the back and front could be different.
Buy the pattern on its own or in Cushy Numbers - a book of 12 patterns
We also have an afghan version of Best of Both Whirls.
