There are plenty of tutorials on the net for making fabric gift bags. I keep a look out for shiny, sparkly, shimmery material to make Christmas bags. This dress was free from the Charity Shop because the zip was put in wrongly and didn't fasten to the top.
I cut off sections to make bags utilising the original seams if possible.
There were only a few bits left over plus a now useable zip and a large belt which could be made into a bow.
The large bag can be just wrapped round a present and tied with a ribbon.
This ribbon was 50p in the sales last Christmas. The spray was from the Charity Shop. The smaller bag I edged with binding found in the junk shop. The button was on the dress and I can't remember where I got the felt.
The real cat couldn't fit in the bag!
