free crochet pattern

espeonnn Is this what you were looking for? 

Thats the best I could find for free. If it were me, I’d crochet a rectangle about 14 inches wide in whatever stitch you prefer and keep going until it’s the height you like (i’d say maybe 2 feet) and then just attach buttons down the side. As long as the buttons you choose can fit between the stitches you’re good to go. 

Hope that helps!!
