Beautiful quilt....

A short cut to piano keys is to sew several different longish strips together ( 3 or 4 ) and then cut them into pieces as wide as your border. Do this with as many variations as you like = groups of strips, cut them up,and mix them up when you sew the qroups of strips into a border.
Saves tons of time! J

I expected to be disappointed when I looked at your first piano key border (after your initial post), but no, when I looked, I liked it a lot. I'd leave it, and bind in black and consider it beautiful!

But I also am confused as to why it took 2 days to do the first side? Are you doing a certain repeat or pattern? I'd just sit and sew strips together, take them to the rotary mat and cut them to size, and combine them. Seems like it would go fast enough that way. I've done piano key borders and that is how I've done them. They are tedious compared to just plain borders, but the effect is great.

But it would look fine without the piano key border, too. I just think it is perfect!!!

I think its perfect and beautiful you did a great job, love the colors

It's beautiful! I did one very similar for my grandson and added a black border. The picture is small I'm sorry, but you can see the border here and I think it will help you decide:

Ditto!

I do love the piano keys, but would save them for a quilt with simple blocks. I would pick a bright color that shows up frequently like red, orange or a bright blue (it's hard to to tell from the photo). Then I would end it with a wider black border.

I love the piano key border, I think it goes with the theme of the quilt top really well.

You might put another solid color border (small like the black one) before the piano keys to separate it from the body of the quilt, but I LIKE the piano keys!

Unless you need the extra size, I would leave it with just the black outline and do a black binding. But then I'm not a big fan of borders, having grown up with quilts from the 30's and consiously or unconsiously feeling that's what a quilt is supposed to look like.
