Tomii, bakakanadajin, I'm not sure how helpful a template that is using one horizontal line for each character is since, as I'm sure you know, it isn't quite the same as vertical writing. Specifically, the っ goes in the top right corner in vertical writing, not the bottom as in horizontal.
I don't think it will make that much difference with these characters, but you may also want to copy from handwritten examples of the characters.
Type "handwritten hiragana" into goggle for lots of examples.
