I've seen some darling patterns for light sweaters or cover ups that would work well for summer. It doesn't really ever get hot where I live so it's always at least sweater weather.
A young man locally has a love for knitting and started a program called "Knitting for Newborns". He made little hats for the babies born at the hospital he works at. The program has really taken off. I believe that hats are now also made for the hospital's cancer patients.
Keep in mind that there are plenty of nursing homes with patients who would love a cozy blanket. If you have a VA hosptial near you, they always have volunteers who make things for the patients and the patients love them. My grandfather was in a VA hospital and some of the blankets that were made for him have been passed down to my children. Grandpa's not here anymore, but the blankets and the love that were put into them are.
You can put your love of knitting to good use, for sure.
My sister and I visited a lovely yarn shop and they had so many catalogs of patterns.
Knitting doesn't have to be just for winter.
Best wishes!
