No, I'm Pat on the Hill from the UK! That is a very beautiful version of Storm at sea, and I think a wavy border would detract from it. I didn't realise it would be so large! I think the narrow, dark border you have included in the drawing is just right.
The only thing is. I think you have done exactly what I did, when I made a small one - I figured out a block, and repeated it. However, as I understand it, the sashing with the diamonds, should not be repeated on both sides of the centre part of the block.
If you check on Google/Images, you will see that there is only one long diamond between the centre parts of the blocks. Do have a look - the first page should be enough; I did just check for you.
Can you have another go, and treat the sashing as a separate entity from the centre part? . In message , Michelle C writes
