Here’s a kind of different purposed bag pattern. A cute little bag to store your mug on the go. This bag will suit for an evening walk on a holiday. Isn’t it? The free pattern is shared as a pdf at Red-Brolly which is a blog of a mother-daughter united. You can get the free pdf pattern for this butterfly mug bag from HERE.
Update: Unfortunately the page which has this pattern is down for several months. Because of that reason I decided to share the pattern in my site. Here is the pdf pattern for this Butterfly Mug Rug. You need to download all three pdfs to get the full pattern.
