Well it all depends.
Making a hood less 60″ long draw cord foot bag with a baffled 48″ zipper is a piece of cake. Â I can make something like this for about $90 over the cost of everything. Â For a simple quilt that size, it would only be about $70 over cost. Â Good thing about this is that you get to choose whatever fabric and down-fill you want.
It seems however that everyone wants all the bells and whistles thrown in to make their quilts resemble a katabatic.
Just throwing a hood on and you’re taking at least 40% more time to make.  The complications of everything coming together at the top of the zipper are ridiculous.  It came to a point where I didn’t do them anymore because you end up fixing so many mistakes and have to bite it on all the price returns from time spent fixing everything.
So I stick to making quilts or hoodless bags. Â If you’re still interested, let me know.
