Oh yeah...Joanne's idea of ornaments works too.
Now that I see it like that...it actually reminds me of sea plants.
Try stamping it without the branch. Make a wreath.
But hey-if you don't like it-there is no law saying you HAVE to keep it. I give you permission to give it away or donate it.
BTW...no offense but I would clean it. The picture you showed us had a lot of ink on it-which might give you thicker lines? Might look nicer clean and dont press as hard. You might get thinner lines. Try a dye ink. The ink on there looked like a pigment which is thicker.
