there is no (average) in my world....sometimes i may (throw together) 2 or 3 in a week- some take me 4-5 years or more---in a pinch i can put together a quilt in a weekend if i need to- i don't do many small quilts 95% of mine are queen or king sized & i don't do easy patterns often unless it's a special request- but it still depends on the project- between the donation quilts (downey quilts for kids, the women's resource center shelter mostly) the gifts & the sales i make 15-50 quilts a year...some years are more (productive) than others- some months are busier than others...i may set a week aside to put together donation quilts & make 10 in that week- then i may not make another quilt for 2 or 3 months...i am always working on numerous quilts at one time & sometimes they are (in progress) for 3-4 months-then all of a sudden i may have 6 come together seems like all at once...then a week of quilting them & bindings...it's all an ongoing thing= with no rhyme or reason.
