Baby blanket of original design in strips...should I attach a border when I am done or not?

my cousin’s wife is due in December with her first child and does not want to know what she s having, so the baby blanket that she has commisioned for me to make will be in mint green and light yellow stripes (made in strips, to be sewn together later). I want to do an original pattern for the blanket, and since babies love texture, I want to do different stitch types for the different color strip(e)s.(two different types of stitches for the two different colors of strips). Purl ridges and moss stitch or seed stitch and moss stitch were my ideas for the blanket. (one for one color and one for the other color). I want to do the strips in about the same width that the strips were in the blanket that I am seaming right now (about 5-5 and a half inches wide, so about 27-29 stitches to cast on for any strip). I want to do it green, yellow, green, yellow, green, yellow ( I want to make six strips) as the order of placement for the strips when I seam it together. I want to do a border for the blanket but im not sure if it is necesary. If I do a border, I thiought about doing a scalloped eyelet edging or a basic lace trim (enough to go around all four sides) in green. I want the finished dimensions to be somewhat like that of the Heirloom Knit Baby blanket (the blanket that I am seaming together right now).
(note to all members reading this- all of the stitch type patterns are on lion brand’s website under the FAQ in stitchfinder).

I used a seed stitch border around the feather and fan baby blanket I recently finished. I don’t have a photo of it on a web site or I would put a link to it. But since you are thinking of using seed stitch as the pattern in the field of the balnket, use the feather and fan sttich as the lace border. Just remeber that the stitch repeat is 18 stitches for each repeat.
My blanket was 15 repeats with side borders of 15 stitches in seed sttitch.

I don’t know much about knitting blankets, I’ve only been knitting for a few months, however I’ve been crocheting baby blankets for 13yrs & never with a pattern (I didn’t learn to read patterns until I started knitting). I’ve made a few strips & squares blankets & used a 3rd color (usually white) to sew the pieces together & also for the border. I’ve found the favored edging from babies is either fringe to chew or holes to stick their fingers through (parents usually prefer the holes over the fringe for the same reasons :wink: ).

The last one I did for my nieces baby boy was knitted in garter stitch strips of alternating colour and I crocheted the strips together (wrong sides tog) then crocheted 6 rows around the edges alternating the colours used in the blanket. It came out looking quite cool.

I decided on using a simple lace border
i have attached an illustration of what it will look like, at least colorwise, when it is finished.

I would go with a border too.
