Another crochet cushion

Following on from last weekends experiment with cushion covers, this weekend I made another cushion using a square of crochet I made in June.  I used the wool that came with Let's Get Crafting Knitting & Crochet Magazine issue 60 and used the pattern for the Shell Cushion cover from issue 56 from Let's Get Crafting Knitting & Crochet Magazine.

This is the cushion.  I made some changes from last weekend's attempts.  My fabric ruler and rotary cutter had arrived from Amazon.  I cut a square 40cm x 40cm and it was very square this time (unlike last weeks)  I cut two pieces for the back 40cm x 30cm.  The crochet square was backed by the square piece of fabric and the back pieces overlapped like last week.  The slightly bigger pieces made for a much better overlap than on the last two cushions.  I don't have a walking foot for the sewing machine yet, and I had the same problem as last week with the top layer of fabric moving as I sewed all the layers together.

On finishing the cushion I then made two button holes and attached two buttons to match the colours in the cushion cover.  I like the effect of the crochet, it has a look of an argyle jumper, even though it is the crochet shell pattern. I would like to sell crochet cushions like this on the Internet for £15 per cushion. I feel this is a realistic price and it does offer some profit on the cost of making the cushion.  What do you think of the cushion?  Would you buy one?  Would you pay £15 for it?  Let me know what you think.
